随着公路建设的发展,岩溶作为一种典型不良地质现象在公路施工建设中的危害越来越大。采用高密度电阻率法与对称四极测深法相结合的方法进行岩溶勘察,取得了明显的效果。具体做法是先进行高密度电阻率法工作,在高密度电法视电阻率剖面发现地下电性异常处或影响工程安全性的重点位置,采用对称四极测深法进行进一步勘探工作,发挥了两种方法各自优点,提高了勘察质量。高密度电法资料处理采用经验系数法与测深曲线切线角度法相结合的方法。作为一种较新的资料处理思路,采用高密度电法测深曲线切线角度法,在以往高密度电阻率法数据采集处理基础上,实现了一种工作方法,多种解释手段的综合解释方法,提高了岩溶解释精度及其准确性。
With the development of highway construction, karst as a typical adverse geological phenomenon in the construction of highway construction more and more harmful. The karst survey was conducted by the combination of high-density resistivity method and symmetrical quadrupole sounding method, and the obvious effect was obtained. The specific approach is to first conduct the work of high-density resistivity method, in the high-density resistivity resistivity profile of the discovery of underground electrical abnormalities or affect the safety of the key positions, the use of symmetry quadrupole deep exploration for further exploration, play The advantages of both methods improve the quality of survey. The method of high-density electric method data processing is a combination of empirical coefficient method and sounding curve tangent angle method. As a new idea of data processing, the high-density electrical method sounding curve tangent angle method was used. Based on the data collection and processing of high-density resistivity method in the past, a comprehensive explanation method of working method and interpretation methods , Improve the interpretation of karst accuracy and accuracy.
