摘要
在岩溶区和煤炭采空区路段发生路面开裂下沉。分析其成因以及岩溶塌陷和采空塌陷诱发路面变形的破坏形式、变形量和致灾规律。并利用高密度电法、地震和钻探进行验证。
Crack and subsidence occur on sections through Karst and coal mined-out areas. The article analyzes their cause, destruction form and deformation amount of the road caused by Karst or god collapses, and disaster law. Meanwhile, high den- sity resistivity, seismic investigation and drilling are used to verify the study.
