高密度电法在输电线路地质分层中的应用

Application of High Density Resistivity Method in Geological Stratification of Transmission Lines

输电线路通常穿越地质环境复杂的区域,其沿线地质情况决定着塔基排布与走向。以湘西自治州—娄底500 kV超高压线路工程为研究对象,通过采用高密度电法对沿线塔基开展地质调查并获取地层剖面,结合地质钻探结果进行对比验证。结果表明,采用高密度电法能较为准确地获取地质分层情况。研究结果可为类似区域性输电线路工程勘察提供借鉴。

Transmission lines usually pass through areas with complex geological environment, and the geological conditions along the lines determine the layout and direction of the tower foundation. Taking Xiangxi Autonomous Prefecture—Loudi 500 kV EHV transmission line project as the research object, the geological survey of the tower foundation along the line is carried out by using high density resistivity method, and the stratigraphic section is obtained, which is compared and verified in combination with the geological drilling results. The results show that the geological stratification can be accurately obtained by using high density resistivity method. The research results can provide reference for similar regional transmission line engineering investigation.
