西南某桥基边坡稳定性及加固措施研究

 桥基边坡由桥基、桩基和边坡组成复杂的桥基结构体系。其变形和稳定性要求、加固措施以及重点加固部位与自然边坡有很大的不同。针对我国西南某特大桥桥基边坡，结合数值模拟以及极限平衡分析方法，对桥载荷作用下边坡破坏模式、预应力锚杆加固对限制水平位移的作用、利用基桩作为抗滑桩以节省加固工作量的可行性，以及重点加固部位等问题进行了深入分析，最后提出了加固措施。

Bridge Foundation Slope Stability and Reinforcement Measure of Some Bridge in Southwest

Bridge foundation slope is a complex structural system composed of pile foundation and slope,in which its deformation and stability requirements,reinforcement measures and key reinforcing positions are significantly different from natural slope.In combination with the foundation slope of some bridge in southwest,some problems,including the failure mode of slope under bridge load,the restriction effect of prestressed anchor bars on horizontal displacement,the feasibility of making foundation piles as anti-sl...
