水工隧洞复合衬砌变形研究

Study on Deformation of Composite Lining of Hydraulic Tunnel

文章以云南临沧市某无压输水隧洞复合衬砌结构设计为例,利用ANSYS软件进行建模,分别对比初始地应力及考虑衬砌与围岩联合承载作用下的模拟成果,研究水工输水隧洞衬砌结构的变形特征,以期对同类型的输水隧洞设计施工提供一定的指导意义和参考价值。

This article takes the design of a composite lining structure of a pressureless water delivery tunnel in Lincang,Yunnan as an example,uses ANSYS software for modeling,compares the initial in-situ stress and considers the simulation results under the joint bearing of the lining and surrounding rock,and study on the deformation characteristics of the lining structure of hydraulic water conveyance tunnels is expected to provide certain guiding significance and reference value for the design and construction of the same type of water conveyance tunnel.
