一体式扶壁挡墙地下结构受力分析研究

Study on stress analysis of underground structure of integrated buttress retaining wall

对于狭长型下沉式广场等敞口埋地结构而言,邻土侧挡墙呈悬臂状态,为解决挡墙顶部变形过大、结构整体抗浮及结构防水问题,采用主体结构、扶壁式挡土墙结构一体化的设计思路。本文运用sap2000对该结构形式进行受力分析,得到结构受力变形性状及计算设计模型。

For the upper open buried structures such as the narrow and long sunken square,the side wall adjacent to the soil is in a cantilever state.In order to solve the problems of excessive deformation at the top of the side wall,the overall anti-floating of the structure and the structural waterproof,the design idea of integrating the main structure and buttress retaining wall structure is adopted.In this paper,the mechanical analysis of the structure is carried out by using sap2000,and the mechanical deformation behavior and calculation design model of the structure are obtained.
