预应力技术在土质边坡工程中的应用

Application of pre-stressing technique to earth slope engineering

在土质边坡稳定分析或加固方案设计时,常采用计算机软件进行边坡稳定计算。在实际工程应用中,现有很多边坡稳定分析软件除输入土的物理力学参数和边界条件以外,有时还需要采用预应力加固措施。为了制定经济高效的预应力加固方案设计,需要丰富的工程经验和专业技巧。文中对使用稳定分析软件时有关预应力等问题进行了讨论。

During stability analysis or design of slope strengthening, the relevant software is usually used for the calculation of the slope stability. However, within the actual applications of many softwares for the analysis on the slope stahihy, not only the physical and mechanical parameters of soil body and the boundary conditions concerned must be inputted, but the pre-stressing strengthening measurements must also be adopted occasionally. In order to make an economic and efficient pre-stressing strengthening scheme, rich engineering experiences and professional techniques are necessary. The related pre-stressing problems from the use of the stability analysis software are discussed herein.
