Abstract:The new reaction force wall experimental system in a structure laboratory includes L-shaped reinforced concrete reaction force wall and box-shaped earth anchor room. The structural testing platform is 14-700m long and 11-000m wide, and the reaction force wall is 12-0m high and 2-500m wide. According to the design indexes and mechanical characteristics of the reaction force wall experimental system, the reasonable structural layout was presented. The overall model of reaction force wall experimental system was built by using FEM programs of ABAQUS and MIDAS Gen to conduct bearing capacity, deformation and stress analyses under the most adverse working conditions. The FEM analysis results indicate that the structural design scheme can satisfy  requirements of all the design indexes.

Keywords:reaction force wall structure; finite element; deformation
