Abstract
According to the characteristics of double line added to the existing line which is in parallel to the cutting with developing groundwater in K53 Section of Nanjing-Qidong Railway, the necessity of using reinforced concrete U-shape groove in the section of the cutting with developing groundwater is analyzed. Currently, U-shape groove is commonly calculated in such manner that the floor plate is analyzed with Winkler Foundation Beam Model and the side plate is calculated by earth pressure at rest with cantilever beam model. In the project of K53 Section, the finite element software MIDAS is used to simulate integral structure of U-shape groove and the plate unit is used to analyze deformation and forcing characteristics of cutting structure ; furthermore, combined with the designs of foundation pit support and foundation treatment, the groundwater seepage in construction and operation period could be solved.关键词
