重庆秀山县岩溶地区公路边坡溶洞治理方案

岩溶地区公路边坡具有地面坡度陡峭,基岩破碎程度高,坡积及残坡积层分布复杂,地下水活跃以及边坡治理施工条件困难等特点。其加固处理不但要考虑溶洞本身的受力情况,更需要考虑边坡的整体稳定性。通过对重庆秀山县岩溶地区边坡中出现的垂直于滑坡面的溶洞受力分析,从边坡的整体稳定性出发,研究岩溶地区公路边坡坍塌的应急加固治理方案。

Treatment Scheme of Highway Slop and Cave for Karst Areas in Xiushan County,Chongqing

Based on a lot of landslide phenomenon theory study,the ground surface slope is steep with higher bedrock fragmentation degree and the distribution of both residual and slope sediments are complicated,meanwhile,groundwater is active,all of which result in difficult treatment and construction condition for slopes.Not only must the stress of the cave but also whole stability of the slop be carefully considered in the slops reinforcing.By analyzing the force applied on the cave that is vertical to the landslide for karst areas in Xiushan county,Chongqing,the emergency reinforcing program of collapses for karst areas is put forward though the whole stability of the slop.
