摘　　要：地下空洞等路基“病害”是引起道路失稳破坏的重要隐患。本文在研究测区地质地球物理条件的基础上 ,采用先进的地球物理技术 (浅层地震法、双频激电法和地质雷达法 )对岩溶地区公路工程地下空洞进行了综合勘察 ,探测结果可为路基病害的评价与处治提供科学依据。Underground cavity is the most important hidden danger to result in losing stability and destroy of highway. In this paper, the author carried out comprehensive prospecting of underground cavities by the advanced geophysical techniques, such as seismic, dual-frequency IP and GPR method, in highway engineering on Karst area on the basis of research on geological and geophysical conditions of working area. The results obtained by author can provide the scientific foundation for evaluating and reasonable treatment of defects under the roadbed.
