Research on Mechanic Characteristic of Waterproof Membrane for Highway Tunnel

Multi-waterproof measures are adopted to highway tunnel, where waterproof membrane is the most vital link between initial lining and final lining during waterproof system. In light of plenty of field monitoring data by compress sensors, the article presents phase and position of the maximal compress stress of waterproof membrane during pouring final lining, and different calculation formula of analyzing self-weight stress and temperature stress of concrete. The article also presents tensile stress condition under surrounding rock bad extra-excavation and stress calculation by finite element method of nonlinear hardening constitutive model. The mechanic characteristic contributes to applied value for simplifying reliability assessment parameters and conducting safety construction for waterproof membrane.
