高密度电法在高速公路地基稳定性评价中的应用

Application of High-density Electrical Method in Highway Roadbed Stability Evaluation

在地下以隐伏基岩为灰岩的路基地段,常常伴随着岩溶、土洞的发育,这些不良地质现象对路基稳定性影响很大。本文阐述了高密度电法勘探的基本原理和方法,并通过对梅河高速公路第一标段的勘察成果分析,探讨了高密度电法在高速公路地基稳定性评价中的应用效果,并分析了高密度电法解释误差的客观原因。

The roadbed that undergound concealed bedroak is limestone,usually comes with the growth of karst caves and burrows,and these unfavorable geolocigal phenomenons affect the raodbed stability a lot.This article explains the theory and technique of High-density Electrical Method in exploration,and discussse the application in highway Roadbed Stability Evaluation by analyzing the explorative achievements of Meihe Highway first bid,and investigates the causes that High-density Electrical Method errors come from.
