Aoki, K. and Shiogama, Y., 1993. Geoengineering techniques used in the construction of underground openings in jointed rocks. In: M. Langer, K. Hoshino and K. Aoki (Editors), Engineering Geology in the Utilization of Underground Space. Eng. Geol., 35: 167–173. Examples of underground openings used for pumped storage hydroelectric power stations and storage facilities for crude oil in Japan are described. In these examples the observational construction technique is important to compensate for missing data in the preliminary surveys. Some new drilling and assessment techniques that have been developed are also introduced. 相似文献

Miyake, N. and Denda, A., 1993. Utilization of underground spaces in urban areas: Urban geo-grid plan. In: M. Langer, K. Hoshino and K. Aoki (Editors). Engineering Geology in the Utilization of Underground Space. Eng. Geol., 35: 175–181. The Urban Geo-grid Plan aims for a systematic and better coexistence of above-ground and underground areas through the utilization of underground space presently not in use, without interfering with existing urban functions. There would be “base points” supporting regional functions which are laid out in a grid connected by “lines”. Base points would consist of “grid points” and “grid stations”, which serve as control centers for grid points, the grid points and grid stations being interconnected by tunnels to form an “underground network”. Normally, a base point would be used for multiple purposes to supplement regional functions which are inadequate, as well as urban functions, and in emergencies, such as earthquake disasters, it would demonstrate information and evacuations functions. 相似文献

The Cruachan Underground Power Station was constructed at a depth of about 300 m between 1961 and 1965 within the granitic rocks of the Etive granite ring complex in the southwest Highlands of Scotland. The rock mass is a solid intrinsically strong material with a moderately high residual stress, the ratio between the horizontal and vertical stresses being approximately 1.2/1. The discontinuity system consists of a cuboidal arrangement of fractures. The major joint set parallels a fault which crosses the construction site and such joints are coated by weak, chloritic minerals. The influence of the joints and the natural stress distribution on the stability of the rock mass, and the techniques of stabilisation are described and illustrated. 相似文献

A continent-oceanic island arc collision model was proposed as a new geodynamic scenario for the evolution of the Cretaceous Central Anatolian granitoids in the Central Anatolian crystalline complex (CACC) by Boztug et al. (2007b) [Boztug, D., Tichomirowa, M., Bombach, K., 2007b. 207Pb–206Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust, Turkey. Journal of Asian Earth Sciences 31, 71–86]. The key aspects of this model include an intra-oceanic subduction in the Neotethyan Izmir-Ankara Ocean, formation of an island arc and its subsequent collision with the northern margin of the Tauride–Anatolide Platform. The identical scenario was initially proposed by Göncüoglu et al. (1992) [Göncüoglu, M.C., Erler, A., Toprak, V., Yalınız, K., Olgun, E., Rojay, B., 1992. Geology of the western Central Anatolian Massif, Part II: Central Areas. TPAO Report No: 3155, 76 p] . Moreover, the weighted mean values of the reported 207Pb–206Pb single-zircon evaporation ages by Boztug et al. (2007b) [Boztug, D., Tichomirowa, M., Bombach, K., 2007b. 207Pb–206Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust: Turkey. Journal of Asian Earth Sciences 31, 71–86] from A-type granitoids in the CACC seem to be miscalculated and contrast with the field data. 相似文献

3-D geological modeling plays an increasingly important role in Petroleum Geology, Mining Geology and Engineering Geology. The complexity of geological conditions requires different modeling methods in different situations. This paper summarizes the general concept of geological modeling; compares the characteristics of borehole-based modeling, cross-section based modeling and multi-source interactive modeling; analyses key techniques in 3-D geological modeling; and highlights the main difficulties and directions of future studies. 相似文献

The year was marked by noteworthy advances in multinational consortia of commercial firms and of forward-looking universities. Again, the tenor of the practice of Engineering Geology has picked up. Not to be in the vanguard does indeed mean that one languishes in the dust raised by those on the move. Engineering geologists must understand an infinity of challenges stemming from land development, environmental protection and cleanup and resource development. This is a profession in which age can bring wisdom and increased competence.Most practitioners were busy in 2001; more than 80% of ASFE member companies report that business has increased or stayed the same for the past 6 months. Sixty percent of practitioners expect that their 2002 revenues will be stable or increase for Year 2002. 相似文献

The paper [Wang, J.-J., Zhu, J.-G., Chiu, C.F., Zhang, H., 2007. Experimental study on fracture toughness and tensile strength of a clay. Engineering Geology 94, 64–75.] focuses on two important fracture parameters of soils: tensile strength and fracture toughness. These parameters control the behaviour of soils in a wide range of situations, from the design of a simple footing to much complicated fracture behaviour of clay liners or covers. The authors have done extensive laboratory work to determine these two parameters and their laborious and complicated experimental program needs praise. However, some of the points raised in their conclusions, based on the analysis and comparison with the data from the literature, need to be discussed. 相似文献

在近十年,工程地质学科紧密结合国家战略需求和工程建设的科学技术难题,为国家超级工程建设提供了技术支撑,而且通过理论创新和技术研究,极大减少了因地质灾害而死亡的人数,取得了一大批代表性的理论成果,可以用三句话总结十年来工程地质学科的发展:“奠基超级工程、保障民生福祉、推动学科发展”。但是应当注意到,我国工程地质学的发展还远远不能适应国民经济发展和人民安居乐业的要求,打破学科壁垒,吸收相邻学科特别是现代地球系统科学以及技术科学的最新成果,加强工程地质人才建设,推动学科发展仍然任重而道远。 相似文献

Engineering geology, in 1996, worldwide, was experiencing considerable turmoil due to the uncertain nature of national economies and the general situation of inadequate funds to meet the demands of failing of the national infrastructures that serve citizens. Aside from the previously war-damaged cities of Western Europe, new public service systems of transportation and utilities elsewhere often lagged well behind growth. It will be some time before international aid and civil engineering contracts are initiated for anything other than humanitarian and basic emergency aid work in these areas. Many countries in the western hemisphere, eastern Europe, the former Soviet Union and developing nations in particular are still in need of basic water and sewage services as well as repair and replacement of old existing systems. Continued partisan warfare in the Balkan states of Albania, Bosnia, Croatia and Serbia forecast the eventual need for redevelopment. Rumblings of broad-scale economic problems in Far-Eastern economies did little to make overseas contract opportunities in these areas very attractive. Large consulting firms were challenged by an increasing number of individual and small practices who are prepared to operate on 1970's rates and prices for services and government and industry was taking advantage of that situation. More and more individuals were offering services in engineering geology and associated engineering fields and there was a sense of not having enough work to go around. Hence, price competition was again being promoted. Consequently in both Europe and the Americas, the variability of competence was enlarging and a significant amount of so-called ‘professional ’ work was lacking in overall quality. This was especially evident in ‘Environmental’ areas of work. This begs the question: ‘Is not engineering geology, or any other aspect of applied geosciences, not environmental in nature and essence, fundamentally and in entirety?’ Environmental restoration demands were still being made by governments, but the pressure to complete such work was being relaxed on account of economics. Our clients were asking for more service at lower fees. Clients were still largely unwilling to openly acknowledge that less money spent on competent engineering geologic consultation means that more risk should be accepted by the owner or operator of projects. 相似文献

内蒙古巴彦敖包地区广泛出露上泥盆统安格尔音乌拉组地层,1∶5万土壤地球化学测量工作圈定的31处锂单元素异常与安格尔音乌拉组地层分布范围吻合良好。安格尔音乌拉组地层锂元素的富集与该套地层的原生沉积作用密切相关,未发生次生富集。通过对安格尔音乌拉组地层碎屑物源区及沉积作用的研究,认为其锂元素物质来源与镁铁质火山岩中锂元素的侵蚀溶出有关。溶出的锂元素被碎屑物中的粘土矿物吸附随后沉积成岩造成区内广泛分布的锂土壤地球化学异常。进而做出推断,研究区内晚泥盆世甚至更早存在大规模中基性火山活动,应该存在大规模古火山机构。提出一种新的沉积型锂矿成矿模式,即古火山机构周边的粘土矿物含量较高的碎屑岩层位在一定构造背景及沉积环境下可以具备锂元素富集成矿的条件。 相似文献
