Analysis of Configuration and Application of Steel Plate-Concrete Subterranean Composite Structural Wall
摘要
Abstract
In order to overcome the inherent limitations of traditional reinforced concrete structures in underground engineering,this paper innovatively proposes an assembled steel plate-concrete subterra-nean composite structural wall.A multi-physical field model is used for the numerical analysis of the local connection and the overall structure of the wall,to simulate the mechanical properties and dam-age form of the connection parts and the lateral displacement of the wall,stress distribution,earth pressure and soil deformation of the wall under the two conditions of construction and permanent use of the wall.The results show that:the shear strength of the joint of the structure is high,and the stress values of the representative joint units developed are all less than the yield strength of the material.The lateral displacement of the wall is kept at a low level.The earth pressure on the sidewalls of the wall shows a nonlinear distribution along the depth direction;and the laying of the footing plate can effectively alleviate the stresses on the wall,reduce the deformation,and alleviate the soil bulge at the bottom of the pit.After expanding and evaluating,the structure has good economy and can be applied to major projects such as subway station,underground garage,municipal engineering well and foun-dation pit support.关键词
