| 摘 要： | 以万宜高速公路为工程背景，运用有限差分分析软件，对框格梁锚杆加固膨胀土路堑边坡进行了数值模拟和设计优化。计算结果表明:边坡坡率对膨胀土边坡稳定性关系密切，锚杆长度、布设角度和锚杆垂直间距等设计参数对边坡的变形影响显著。根据计算结果，对原设计方案进行了优化，经实施后加固效果很好，可供其他类似工程设计提供参考。

| Abstract: | Taking Wanzai-Yichun Highway as the engineering background, this paper used finite difference analysis software to conduct numerical simulation and design optimization for expansive soil cutting slope reinforced by bolt frame pier. The calculation results show that the slope ratio closely relates to the stability of expansive soil slope; and the design parameters, such as bolt length, fixing angle and vertical spacing of bolts, have significant influence on the slope deformation. Therefore, the original design scheme was optimized depending on these results, and then proved to have good reinforcement effect through implementation, offering reference to other similar engineering design. |
