勘察物探一体化工作方法在岩溶地区勘察中的初步应用及展望

Preliminary Application and Prospect of Exploration and Geophysical Integrated Working Method in Karst Area Exploration

岩溶地区地质情况复杂,岩溶、断裂带、破碎带等不良地质条件发育,传统的勘察手段较难实施且成本巨大,得到的结果对解决实际工程问题效果甚微。通过贵阳市轨道交通3号线花果园西站山岭深埋车站这一典型的岩溶地铁车站工程内,将高密度电法与钻探相结合,通过对比、验证及不断修正物探解释异常结果,使该车站工点的勘察成果最大限度地符合工程实际情况,为设计解决车站岩土工程问题提供重要依据,为岩溶地区类似工程提供了可行的勘察物探一体化工作方法,并对勘察物探一体化工作方法进行了展望。

The geological conditions of karst areas are complex,and the unfavorable geological conditions such as karst,fault zone,and broken zone are developed.The traditional survey methods are difficult to implement and the cost is huge.The results obtained have little effect on solving practical engineering problems.In a typical karst subway station project,Huaguoyuan West Station Shanling Deep Buried Station of Guiyang Rail Transit Line 3,the high-density electrical method is combined with drilling,and the abnormal results are explained by comparison,verification and continuous correction of geophysical exploration.The survey results of the station site are in line with the actual situation of the project to the greatest extent,providing an important basis for designing and solving the geotechnical engineering problems of the station,and providing a feasible method for the integration of survey and geophysical exploration for similar projects in karst areas.
