摘要
针对鹰厦线K290+795~905段路堑边坡建立稳定性分析模型,并开展有限元数值计算.通过分析坡体各段的受力情况,得到各个单元的主应力及剪应力大小,并结合极限平衡计算分析了坡体稳定性,论证了降雨作用下容重、内摩擦角变化对坡体稳定性的影响,探讨了设置抗滑桩前后及其在降雨作用下的抗滑工程效果.
On the basis of in - situ survey, the FEM calculation model of K290^＋795～905 slope along Yingxia Railway is established. By the calculation, the stress, which includes the σ1max and τmax, at every segment in slope is analyzed. Furthermore, combining to the limit equilibrium method, the stability effecting factors, such as unit volume weight γ, friction angle φ and cohesion c are discussed. At last, it is indicated that using anti - slide pile is vely necessaly and has good an effectiveness.
