复合式隧道衬砌防水层的变形和力学特性

Deformation and Mechanic Transmission of Waterproof Tube of Complex Tunnel Lining

采用Ｒ．Ｇｏｏｄｍａｎ单元模拟防水层，对复合式隧道衬砌防水层的变形和力学特性进行了数值分析。发现防水层在传递层间力的同时，还传递剪应力，使复合衬砌结构表现出介于叠合梁和单体梁之间的力学特性。

Simulation is conducted of the waterproof tube by using R.Goodman Element and numerical analysis is made of the deformation and mechanics of the waterproof tube of the complex tunnel lining.The tube is found not capable of transmitting intertube stress,but also of transimitting shear stress, thus rendering the complex tunnel lining structure of mechanic properties between those of polybeam and those of single beam.
