水资源是人类赖以生存的不可替代的物质基础,在全球经济和社会可持续发展过程中占有相当重要的地位。近年来,随着工业和农业的快速发展以及城镇人口的快速增长,随之而来的石油类污染、纺织印染污染、城市垃圾和生产生活污水的不合理处置以及农业生产农药、化肥的大量使用,造成本来有限的地下水污染状况日趋加重。以20世纪80年代时期地下水水质测试资料为背景,利用2015年以及近年来取得的大量水质测试资料,采用"污染指数法",对山东省滨州市进行区域地下水污染综合评价。研究表明:滨州市地下水无机污染以硝酸根、亚硝酸根、氯化物和硫酸盐为主,有机污染以二氯甲烷、三氯乙烯、1,1-二氯乙烯、三氯甲烷为主。相比而言黄河以北地区因地下水水位埋藏较浅,包气带岩性以砂岩为主,而且化工和皮革鞣质加工企业较多,因此受到有机污染危害更大一些。  相似文献

青岛市水资源可利用量远远满足不了区内经济快速发展的需要,水资源缺乏已成为青岛市最突出的问题之一。大沽河水源地是青岛市最大的供水水源地,易采易补,本文在以往工作成果的基础上,结合大沽河水源地的水文地质条件,按照在枯水年系列中动用的储存资源在丰水年能够得到补偿的实践经验和思路,对大沽河水源地的地下水资源潜力进行了全面分析,提出新增地下水人工调蓄资源潜力54.54×106 m3/a,为青岛市增大可供水量、缓解水资源供需矛盾提供了后备水源。  相似文献   

The LUSI mud volcano triggering controversy: Was it caused by drilling?     

Nurrochmat Sawolo  Edi SutrionoBambang P. Istadi  Agung B. Darmoyo 《Marine and Petroleum Geology》2009

Following the Yogyakarta earthquake on May 27th, 2006, the subsequent eruption of a mud volcano has been closely observed and analyzed by the geological community. The mud volcano, known as LUSI, began erupting near the Banjarpanji-1 exploration well in Sidoarjo, East Java, Indonesia. LUSI offers a unique opportunity to study the genesis and development of a mud volcano.  相似文献

滇05井水位动态的震前短临异常     

刘国寿 《地震研究》1998,21(3):282-285

本文根据滇０５井的观测情况,研究该井水位变化速率。经多元回归分析,发现该井水位变化受固体潮汐的影响是主要的。继而采用彼氏滤波方法,排除固体潮汐的影响,结果发现：滇０５井在中强地震发生前,水位动态反映出明显的短临异常。  相似文献

土壤-植被-大气系统水分能量传输模拟和验证   总被引：21，自引：0，他引：21  

莫兴国 《气象学报》1998,56(3):323-332

本文建立了包括地下水的土壤－植被－大气系统水分能量传输综合模型,并对模型中冠层动量湍流交换反梯度传输现象的描述进行了改进。在此基础上,依据冠层内动量和热量的交换以及辐射传输过程,同时求解地表、冠层能量平衡方程,进而模拟饱和－非饱和土壤的水热传输。用浅地下水地区冬小麦田间试验资料对模型进行验证,结果表明,系统能量平衡各分量和土壤含水量的模拟与观测结果相当一致。模型敏感性分析发现,叶面积指数对总蒸散量的影响随叶面积指数的增加而逐渐减弱;叶片最小气孔阻力对总蒸散量的影响,在该阻力较小时更显著;地下水位对蒸散量的影响在它小于１．５ｍ时不显著,而在１．５～１．７５ｍ之间时,蒸散减小较快,主要由于土壤蒸发减小显著,冠层蒸腾稍有增加。  相似文献   

Voltammetric characterization of Boda Albitic Claystone. Comparison with previous Mössbauer spectroscopy results     

《Applied Geochemistry》2016

We used ‘Voltammetry of MicroParticles’ to investigate electrochemically samples from the Boda Albitic Claystone, a potential site for deep underground disposal of nuclear waste in Hungary. The samples were collected near the surface and at a depth of 1050 m. The electrochemical characterization in acidic media allowed the identification of Fe²⁺ and Fe³⁺ ions associated with clays, hematite and pyrite. The cathodic detection of pyrite does not raise special difficulties, but the anodic one is complex and depends on the time of the samples exposure to the atmosphere. This work completes a previous Mössbauer spectroscopy study by clarifying the presence, or absence, of extremely small amounts of pyrite in some samples.  相似文献   

Subsurface geological-geotechnical modelling to sustain underground civil planning     

F. de Rienzo  P. Oreste  S. Pelizza 《Engineering Geology》2008,96(3-4):187-204

The aim of the paper was to document the use of 3D subsurface geological-geotechnical modelling to optimise the planning and development of subsurface structures in city areas. The proposed procedure was applied to the analysis of the subsoil of the City of Turin (Northern Italy). The results of more than 300 boreholes were analysed to develop a model of the geological setting up to a depth of 60 m from the surface. The cementation variability of the alluvial sediments was also spatially described and the influence of this aspect on the soil excavation resistance was highlighted. In order to face the need of archiving, correlating and analysing a large amount of data, a 3D GIS (Geographical Information System) was used to better manage the model and to achieve a useful methodological reference that would be available for the planning and construction of future underground works.

A portion of the geological model, related to the centre of the city of Turin (Italy), was chosen to set up a more detailed geotechnical model, based on laboratory tests and back-analysis procedures, as data input for some engineering applications.

Two case studies were performed concerning:

– analyses used to forecast the subsidence induced on the ground surface by the excavation of the metro line;

– the influence of the works of the metro line on the new Underground Railway Link (interference between two important underground works).

A comparison between the forecasts of the degree of cementation, supplied by the 3D model along a metro tunnel tract, and the excavation specific energy effectively absorbed by the head of the boring machine is reported to testify the reliability of the model of the subsoil of Turin centre. This comparison shows the good reliability of the model and its potential to choose of the optimal boring machines for the future development of the Underground Metro System in Turin.  相似文献
