综合物探方法在复杂高边坡地质勘察中的应用效果探讨
|
摘要
复杂地质边坡基岩出露、高差大、岩溶裂隙和冲沟发育都是进行正常物探测试的不利条件,严重影响了物探测试效果。本文通过介绍和分析高密度电法、井间电磁波和地震波层析成像技术、超声波等多种物探方法的测试效果,总结出在岩溶、溶蚀槽、裂隙较发育地区比较适合采用高密度电法、井间电磁波层析成像以及钻孔岩芯、岩体超声波测试相结合的综合物探方法。讨论各种物探方法在复杂地质边坡中的适宜性,指出造成测试效果不理想的原因所在,对复杂边坡地质勘察有一定的指导和借鉴意义。
There are many adverse conditions to geophysical survey in complicated geological high slope such as bedrock exposedness,big height difference,karst fracture,gully growth and so on.Furthermore,these conditions have a bad influence on the effect of geophysical survey.The paper introduces and analyses several geophysical methods,for example high-density resistivity method,well electromagnetic and seismic wave tomographic technology and ultrasonic test.It is effective to adopt integrated geophysical methods in the complicated high slope.In addition,the paper indicates the reason that well seismic wave tomographic technology is not suitable for the complicated high slope.The conclusion has definite direct and significant reference for the geological exploration for the complicated high slope in future.
