预应力锚索工作性状数值模拟分析

预应力锚索作为一种有效的岩土体支护技术,在软土场地中的应用较少,但是该结构的经济性较好,在一些软土基坑支护中得到应用.为了分析预应力锚索在软土场地中的工作性状,通过数值模拟手段计算了预应力锚索的轴力分布、锚固段长度的影响等问题,得出锚索在岩体和软土中的工作状态存在差异,因此实际应用中应区别对待.

Numerical Simulation Analysis of Working Properties of Prestressed Anchor Cables

As an effective rock and soil support technology,prestressed anchor cables are rarely used in soft soil sites,but the structure is economical and has been used in some soft soil foundation pit support.In order to analyze the working behavior of the prestressed anchor cable in the soft soil site,the axial force distribution of the prestressed anchor cable and the influence of the length of the anchoring section were calculated by means of numerical simulation.There are differences in working status,so they should be treated differently in practical applications.
