Investigation of a landslide in the new site of Badong County by integrated geophysical survey     

LIU Song  ZHANG Shuangxi  Li Jiangfeng 《中国科学D辑(英文版)》2001,44(5):426-436

An integrated geophysical survey which combines vertical seismic profile method, shallow reflection seismic method, electric sounding, soil temperature measurement and radioactive gas measurement was used to investigate Zhaoshuling landslide in the new site of Badong County and to assess the stability of the landslide. By rational use of these methods together with borehole geological profile and other geological information, the spatial distribution of the landslide body, the formations and structures within and without the landslide body were determined and the stability of the landslide was also assessed, thus making great contribution to the successful and rational investigation and assessment of the landslide.  相似文献   

Groundwater quality monitoring system in zones of infrastructure facilities     

G. Rasula  M. Rasula   《Engineering Geology》2001,60(1-4):351-360

Protection of groundwater already is and will also be in the future, a particularly important environmental, socio-economic, social welfare and political task. The fact that the costs of preventive measures are 10–20 times lower than the funds needed to clean up and revitalize polluted aquifers, as well as the fact that the area to be occupied with transport communications and other infrastructure facilities will aggravate protection, both call for an urgent introduction of modern methods of monitoring and preserving all the existing and potential groundwater resources. The basic principle of groundwater protection against pollution means constant control and preventive measures of protection, namely prevention of incidental and other kinds of pollution. The very construction of communications and all accompanying facilities changes and degrades the existent natural geological environment, and when in use they may become structures in whose immediate surrounds surface and ground waters may be polluted by the toxic and waste substances transported. The experience gained through the following activities: the ‘pilot model’ for groundwater monitoring in the zone of Makis, the investigations and monitoring of critical sites polluted with xylene (CIP, Belgrade, 1994/95), and information on the latest achievements in this field in the world (obtained while working on the study of methodology of hydrogeological investigations needed for groundwater quality monitoring system — Jaroslav Cerni Institute for the Development of Water Resources, Belgrade, 1998), stresses a necessity to obligatory design and construct operational systems for groundwater quality monitoring, particularly in the zones of infrastructure facilities (roads, railway, gas pipelines, oil pipelines), which can be considered as potential linear polluters. In that light, this paper is a contribution to developing hydrogeological investigation methodology for designing and operating a monitoring system in the zones of roads, and its legal and practical incorporation in the technical documents of each project. Besides, an emphasis is put on multidisciplinary approach to system implementation, its full automation, rational management, and effective and optimal measures for groundwater protection.  相似文献

殷长春 《吉林大学学报(地球科学版)》1992,(1)

研究发现,瞬变测深法研究深度除了与采样时间(采样间隔,起始和终止采样时间等)有关外,还与信号源强度、大地电导率、系统噪音水平以及仪器观测精度等因素有关,文中对研究深度与这些量之间的关系作了数学描述。  相似文献   

瑞典硫化物矿山尾矿淋滤水的控制     

Axel.  CL 乔永胜 《煤田地质与勘探》1993,21(1):49-53

在瑞典,硫化物矿尾矿污染水的淋滤造成巨大的环境污染问题。本文概述一项利用天然土覆盖尾矿、最大限度地减少淋滤水的调查报告。研究表明,天然土渗水性是如此之高,以致于起不到明显的隔水效果。天然土盖层只能减少高降雨量期或迅速化雪期的渗水量,而且只对淋滤水峰值有作用。但是,作为一种蓄水体,位于尾矿顶部的密封盖层具有重要意义,它可以增加蒸腾损失。  相似文献

可控源音频大地电磁测深法应用实例   总被引：8，自引：2，他引：8  

黄力军  陆桂福  刘瑞德 《物探化探计算技术》2006,28(4):337-341

目前对电法的探测深度要求越来越高,常规电法有时难以满足实际工作需要。与常规电法相比,可控源音频大地电磁测深法具有探测深度大、设备相对轻便和横向分辨率高等特点,已广泛应用于地热资源、水文地质、有色金属矿产和工程地质勘查工作之中,并取得了令人十分满意的实际应用效果。这里介绍的是一些具有代表性可控源音频大地电磁测深应用实例和应用成果,这些实例基本函概了目前电法的主要应用范畴,常规电法难以胜任的地质调查工作。实例中包括断陷盆地型地热资源和深部基岩裂隙水调查,危机矿山深部找矿和复杂地形条件下铁路隧道工程勘查。  相似文献
