摘要
采用有限元数值计算软件 ANSYS6.0对某大型花岗岩深基坑边坡工程进行了二维有限元分析 ,在了解该边坡变形受力规律基础上 ,为克服过去支护设计中土、岩不分的问题 ,采用新的国家规范进行了该花岗岩边坡的预应力锚索支护设计 ,该法与传统支护设计相比可降低成本 3 0 %左右 ,且支护后的变形监测表明该法安全。
The numerical simulation software ANSYS 6.0 is adopted in the analysis of the stability of granite deep foundation pit slope. Based on the slope deformation rule and the new national standard, this paper brought out a pre-stressed anchorage cable supporting design which differentiates rock from soil. By doing so, the cost is reduced, both safety and reliability are proved by deformation monitoring.
