某高速公路路基沉降加固处治设计

The Subgrade Settlement and Reinforcement Design of A Highway

以某高速公路路基沉降路段为依托,分析路基沉降原因,经比选采用高压旋喷桩加固路基沉降路段,同时完善线外排水工程,成功控制路基沉降变形,取得良好的处治加固效果,可为类似工程提供一定的参考。

Based on a highway subgrade settlement section, this paper analyzed the causes of subgrade settlement, selected the reinforced subgarde subsidence section by high pressure rotary-jet grouting pile through the comparison. It also improved the drainage project outside the line and successfully controlled the subgrade settlement and deformation, which achieved the good treatment and reinforcement results, provided some reference for the similar engineering.
