Study of Waterproof Technology about the Operation of Shield Tunnel in Shanghai

摘要

This article analysis the tunnel water leakage characteristics of the Trial operation of Shanghai Metro on the 7th line. Pointed out that the causes of disease, there are four main areas - engineering design, construction, project supervision, operations environment. Depth analysis of the key of the operations of leakage is segment structural cracks, surface subsidence, segment shrink, protected area management, train vibration and other factors and corresponding measures proposed water.
