摘要
以一特定隧道的围岩参数及衬砌参数对CRD和CD工法下的衬砌结构内力及变位进行了模拟分析,分析结果认为:在此特定隧道围岩条件下,将CRD工法改为CD工法,其结构内力和变形在结构的承载能力之内。
The paper carried out the simulation analysis of the internal forces and the displacement of the CRD and the CD working method using a tunnel＇s rock parameters and lining parameters. The analysis results show that the internal forces and the displacement is in the carrying capacity of the structure after the change from CRD to CD under the rock condition.
