城市下穿隧道封闭段结构受力分析

Castle city bottom drilling path sealed stage structural force analysis

城市下穿隧道结构安全是保证下穿隧道建设及日后正常运营的重要条件之一。以茶坑隧道为例,运用MIDAS软件,采用荷载—结构法进行断面数值模拟分析,详细探讨了下穿隧道结构的应力分布,以指导茶坑隧道设计工作。

The safety of urban underpass tunnel construction is one of the important conditions to ensure tunnel construction and normal operation in the future. Taking the Chakeng tunnel as an example,this paper uses MIDAS software to carry out section numerical simulation with loadstructure method. The stress distribution of the underpass tunnel structure is analyzed in detail to guide the design of Chakeng tunnel.
