东楼隧道左洞出口病害成因分析

Analysis of the causes of defects in Donglou left tunnel exit

文章采用有限元计算的方法对东楼隧道施工中病害进行分析,通过不同施工工序给隧道结构体系所带来力学上的差异,揭示了施工工序对隧道结构体系稳定的重要性,同时也表明理论分析计算在隧道设计和施工中占有重要的地位。

By means of finite element method this paper analyzes the causes of defects in Donglou tunnel during construction. It is indicated that different construction procedures generate mechanical differences to tunnel structure system, so construction procedure is important to tunnel structure system. It is also indicated that theory analysis is important to tunnel design and construction.
