去年上半年,我院承担了连云港核电厂一期核岛、常规岛及海水取排水和人工边坡的工程地质勘察工作.由于是核电厂厂址勘察,业主及设计部门在外业勘察及内业资料处理上提出全部资料采用计算机处理,并提供成果报告的光盘或软盘.这意味着我们的全部成果资料应该是数字化的. 相似文献

瞬变电磁在资料解释中如何消除低阻屏蔽 总被引：1，自引：0，他引：1
常规的瞬变电磁资料处理解释方法是对野外采集的归一化二次电位数据通过公式计算转化为视电阻率值,然后针对各目的层绘制等视电阻率平面图,并通过对平面图的解释圈定出异常区域.由于受浅层低阻屏蔽影响,使得绘制出的平面图从浅层到深层的视电阻率等值线形态非常相似,若浅部存在低阻层,则对深部的异常进行解释难度较大.利用原始的归一化二次电位差值方法可消除低阻屏蔽的影响,该方法在山西潞安集团司马煤业有限公司的应用,验证了其勘探效果. 相似文献

Before construction activities could begin, engineering geological and geotechnical investigations had to be approved in order to establish a map with suitable areas for safe construction. The example used in this study is Tunis City which has complex geology and geomorphology. The risk analysis was based on a large-scale land-suitability map that was prepared using Geographic Information Systems (GIS). The approach used in this study combined physical data with the geotechnical properties of Tunis City. The adopted methodology and analyses were performed to assess the risk of urban expansion and landscape management. Results are presented as a zoning map that shows the suitable area for safe extension of the urban area. The data used and multi-criterion analysis of geotechnical and geological data seems to be useful for similar case studies and the adopted methodology can be used successfully for identifying similar cities for risk assessment. 相似文献

Soil depth reconstruction for the assessment of the susceptibility to shallow landslides in fine-grained slopes 总被引：1，自引：1，他引：0
This paper proposes a methodology aimed at reconstructing the maximum thickness mobilized by shallow landslides in fine-grained soils with the aid of geological and geotechnical analyses. The methodology, implemented within a geographic information system (GIS) environment, is composed of two stages for map reconstruction and two stages for map validation. The first stage of map reconstruction is aimed at individuating the soil thickness on the basis of only topographical and geological analyses; the second stage improves the previously obtained map with the aid of morphological and geotechnical analyses that provide a thickness map usable for shallow landslide susceptibility assessment. This map is validated with the aid of both in situ investigations (stage I), and geotechnical models able to back-analyse shallow precipitation-induced landslides over a wide area (stage II). An application of the proposed methodology is provided for a test area of the Calabria region (southern Italy) that is representative of the Catanzaro Strait, where widely diffused shallow landslides in fine-grained soils systematically occur. The results highlight the usefulness and reliability of the geotechnical models when implemented with the aid of a database representative of fine-grained soils while a secondary role is played by in situ investigations that in the test site have been performed only in a few representative and accessible areas. 相似文献

地电成像法是在普通电法装置的基础上进行高密度的数据采集,形成一个高密度的、内容丰富的视电阻率剖面。通过地电数据分析、处理,可以客观、真实地反映地质体的一些基本特征。由于其具有高效、快捷的勘探优势,近年在岩土工程勘察中应用也越来越广泛。以西虎岭景区勘察为例,简要介绍了地电成像法在岩土工程勘察中的应用。实际应用表明,该方法所得结果真实、可靠,在查明岩溶洞穴、断层、破碎带等不良工程地质现象方面是一种高效、快捷的勘察手段; 相似文献

Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical
and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements
and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone
tests. The investigation shows that there is a correlation between sensitivity and electrical resistivity, which can be used
to discriminate between marine clays that have been leached sufficiently to possibly form quick clay and those for which the
salt content remains sufficiently high to prevent this. Although the most reliable evaluation of the variation in sensitivity
was obtained by the CPT with additional measurement of total penetration force, this investigation suggests that any sounding
method that uses a constant rate of advance into the ground and in which the penetration force applied on the top of the rods
is measured may be used for quick clay mapping. 相似文献

Urban, industrial, and tourist developments are considered of high priority in Egypt. In the current research, the site suitability investigation for rating the different environmental, geological, and geotechnical conditions facing civil engineering projects were assessed using a geographic information system (GIS) multi-criteria approach. The study area is one of the most promising areas for urban and touristic as well as industrial developments in Egypt, which is located on the NW coast of the Gulf of Suez. This area may face several geo-environmental problems that will limit its suitability for civil projects. Weighted GIS model, which integrates different types of data sources, such as land use/cover, geological, geomorphological, geophysical, environmental, remote sensing, and field data, can be achieved to create a site suitability map. In this paper, an analytical hierarchy process approach has been used to develop the weighted model for different factors. As a result of this study, areas of potential geotechnical and geo-environmental hazards that could impact the design and construction of civil projects were identified. Therefore, changes can be made early in the design process before significant design efforts are being invested. 相似文献

上海地区桩基工程勘探中忽视桩端主要持力层范围内相对软弱夹层存在的情况时有出现。文章从第四纪地质角度分析了相关地层组成复杂性的客观因素,它是松散土层垂直相变的反映。同时指出,当前工程勘察工作中现场勘探劳务施工和岩土工程工作脱离、岩土工程师缺乏第四纪地质观念,常以建筑材料观念看待、处理地基土层,以及过分依赖计算机的倾向。建议按ISO9001精神,加强桩基勘探工作的全过程控制。 相似文献
