隧道出口明洞衬砌支护结构的内力计算与分析

通过对某隧道拟建区的工程地质特征进行概述,对该段隧道开挖后的明洞、洞口的衬砌支护的内力进行准确计算和合理分析,并指出该计算分析结果已通过论证,而正在进行施工的衬砌即是按此进行设计的。

Calculating and analysis of inside force of the open cut tunnel lining-up protecting structure

This paper accurate computes and reasonable analyses the inside force about the supports and protections of the open cut tunnel and lining-up protecting in entrance to a cave in the tunnel which will be built,through analyses the engineering geology characteristic of the area in which the tunnel will be built,its points out that this computation and analysis result has been proved,and has been carrying on the construction of the supports and protections is designed according to this.
