摘　　要：小刚度门式刚架型钢劲性水泥土支护结构具有挡土和止水双重功能,运用有限元软件ADINA模拟分析得知,水泥土材料性能、型钢型号、水泥土挡墙厚度和刚架宽度均在不同程度上影响小刚度门式刚架型钢劲性水泥土支护结构的抗变形能力。为小刚度门式刚架型钢劲性水泥土基坑支护的设计理论和施工提供参考。Small rigidity portal frame steel stiffness cement-soil structure has the function of retaining small rigidity material and cement-soil work together to form a dual function of retaining and sealing the foundation pit structures.According to finite element software ADINA,simulation analysis shows that,cement material properties,steel type,the thickness of the cement retaining wall and steel frame width are affected in varying degrees of resistance of deformation of small rigidity portal frame steel stiffness cement-soil retaining structure,and as the Small rigidity portal frame steel stiffness cement-soil retaining structure provide the basis for design theory and construction.
