地质物探综合勘察在水库大坝漏水中的应用
|
摘要
为了能够快速、精确地找到水库坝体漏水位置,提出了地质、物探综合分析勘察的方法。首先进行工区实地勘察,对坝体的工艺、地层的岩性和构造等进行详细调查,深入分析坝体漏水隐患重点区域,进而构建漏水通道;结合地质分析调查成果,利用综合物探方法对水库坝体漏水隐患进行勘查。结果表明:利用综合物探方法对水库坝体漏水进行勘查具有较高的勘探精度;以地质调查为基础,构建大坝地层节理裂隙渗漏通道极大地缩短了物探勘查所耗用的时间、简化了物探勘查施工难度、降低了物探勘查成果的多解性。
In order to quickly and accurately find the reservoir dam leakage location, geological, geophysical comprehensive analysis method was proposed. Working area field investigation was made to investigate dam technology, formation lithology and structure. Key area dam serious leakage was deeply analyzed to build water channel; In combination with geological analysis of the survey results, using the comprehensive geophysical prospecting method investigated reservoir dam leakage. The result showed that comprehensive geophysical prospecting methods surveying was more accurate in reservoir dam leakage; On the basis of geological survey, building the dam ground fissures leakage passage greatly shortened the geophysical exploration time, simplified the geophysical exploration construction difficulty and reduced the uncertainty of geophysical exploration interpretation ambiguity.
