昌金高速公路岩溶路基稳定性的FLAC方法研究

Research on the stability of karst roadbed with FLAC method in Changjin expressway

采用FLAC数值分析方法对昌金高速公路模沙村段路基下岩溶的稳定性及岩溶溶洞对路基稳定性的影响进行了研究，给出了溶洞和路基稳定的条件，以保证公路建设质量。

Using FLAC numerical analysis method the stability of karst roadbed in Mosha village section along Changjin expressway and influences of underground cavity on roadbed are analyzed. Corresponding stability conditions are proposed in order to ensure construction quality of expressway.
