| 摘 要： | 根据郑州市西南绕城高速公路膨胀性岩土路堑边坡在施工过程中的实际破坏状况,将边坡分成四个加固区域,针对不同区域的实际情况采取不同的加固方案.按照不同加固结构的设计参数和坡体自然属性,利用数值分析方法,对加固后坡体稳定性及加固结构承载性能进行了系统分析.结果表明,加固后坡体稳定性得到显著提高,加固结构尤其是自预应力锚杆,表现出良好的承载性能,使得不同类型的加固结构与坡体构成有效的承载整体.

| Abstract: | According to the unstable situation of an expressway cutting slope located in Zhengzhou city of China, four retaining regions were divided by reinforcement design and different reinforced structures were adopted in the four regions. Based on the design parameters of the reinforced structures and the natural mechanical properties of the rock cutting slope, the stability of the cutting slope after reinforcement was analyzed by numerical analysis. The result shows that besides the reinforced structures and the self-reinforced anchor bars perform high loading-capacity, the reinforced structures and the rock cutting slope have come into being a whole integer. |
