甬台温高速公路平苍段路堑高边坡的加固实践

Practice of the Reinforcement of the High-cut-slope of Pingcang Section of Yongtaiwen Superhighway

甬台温高速公路平苍段的路堑高边坡地质条件复杂,松散土体覆盖层厚度大,部分路堑穿越古滑坡体。采用预应力锚索架梁结合抗滑桩和锚杆等方式综合加固,取得了良好的效果,也为今后在类似地质条件下进行边坡加固提供了经验。

The geological condition of the high-cut-slope of Pingcang Section of Yongtaiwen Superhighway is complicated, the thickness of the overburden of the unconsolidated soil body is bigger, and partial through cut crosses the ancient sliding body. The comprehensive reinforcement of the prestressed anchor line supported beam combining the anti-slide pile and anchor stock, etc. is adopted, which obtains good results and provides experiences for the reinforcement of the through cut under the similar geological conditions in the future.
