摘要
我国已成为公路建设大国,公路网日益完善,公路路基的沉降普遍存在于桥头、涵洞等位置。对于山区公路路基填方较大,多为高填方路基,因此在交工验收通车后很容易产生沉降,沉降较大时就会破坏公路结构,产生裂缝病害,直接影响行车安全性和舒适性。因此,需要采取适当措施来进行处理。
China has become a big country of highway construction,and the highway network is increasing day by day.The settlement of highway subgrade is generally located at the bridge head and culvert.For mountainous highway subgrade,the filling is large,mostly high fill subgrade,so it is easy to produce settlement after acceptance and opening to traffic.When the settlement is large,it will damage the highway structure,produce crack disease,and directly affect the safety and comfort of driving.Therefore,it is necessary to take appropriate measures to deal with it.
