摘要
通过对黄土隧道现场调研,测试和资料收集,得到隧道衬砌背后空洞的大小、位置及混凝土衬砌的强度等参数,采用ANSYS软件建立数学模型对隧道衬砌背后有空洞部位进行模拟分析,通过有无空洞的对比,研究空洞大小及所处位置对隧道衬砌受力及变形的影响程度,找出空洞的临界大小及最不利位置.
Based on the loess tunnel site investigation,testing and data collection,get behind the empty tunnel size,location and strength of concrete lining and other parameters,a mathematical model using ANSYS software behind the hole on the tunnel lining parts of the simulation analysis,through the availability of empty contrast,size and location of holes on the tunnel lining by the impact force and deformation to find the critical size of the hole and the most disadvantageous position.
