摘要
利用奥地利岩土工程有限元分析软件FINAL,考虑岩土的弹塑性性能,研究分析了通过提高锚杆区围岩参数模拟锚杆作用的可行性及相关问题,得出了针对土质隧道提高围岩弹性模量和抗剪强度参数40%左右可起到模拟锚杆作用的结论.
Probe into simulation of the bolt function in tunnel analysis by increasing geomaterial parameters is performed based on the finite element analysis. The Austrian FEM software FINAL is employed and the elasticplastic behaviour of the material is considered in the analysis. The result shows the possibility of the simulation method.For the loessal tunnel, increase of 40% of the surrounding soil's parameters can give the same result as FE calculation of using bolt elements.
