摘要
连拱隧道围岩压力的计算与单洞隧道不一样,在《公路隧道设计细则》(JTG/T D70—2010)的基础上对连拱隧道深浅埋分界判断及围岩压力进行了研究。以象山隧道为具体工程实例,对围岩压力进行了计算,并采用midas数值计算软件对衬砌及中隔墙内力进行了计算,得出内力分布图,对连拱隧道设计有一定的指导意义。
The count about rock pressure in arch tunnel is different with a single-hole tunneling. On the basis of ＂highway tunnel design specification＂ （JTG/T D70-2010） ,the article study the boundary judgments of the buried and rock pressure in arch tunnel. With specific examples of Xiangshan tunnel, it calculate the rock pressure, and use midas numerical software to calculate internal forces of lining and wall,and obtain the internal force distribution. It have a certain reference for the design in arche tunnel.
