摘要
深挖路堑支护方案的合理性直接影响到高速公路通车后运营安全。采用新型轻质填料泡沫土处理路桥过渡段的方案,有效解决了高速公路桥头跳车的问题。同时通过定性及定量的方法分析了深挖路堑的稳定性,根据分析结果确定了边坡防护方案,确保高速公路运营通行后的安全性。
The rationality of deep cutting support scheme directly affects the operation safety of expressway after opening to traffic.This paper introduces a new type of lightweight filler foamed soil to treat the transition section of road and bridge.At the same time,the stability of deep cut is analyzed by qualitative and quantitative methods.According to the analysis results,the slope protection scheme is determined to ensure the safety of highway after operation.
