摘要
悬锚式挡土墙是新型的组合式支挡结构。以两层锚定板的悬锚式挡土墙为对象,依据有限元分析结果,研究了悬锚式挡土墙的结构设计和稳定性分析方法。提出了以朗金主动土压力为基础的墙背土压力计算方法。给出了墙身结构设计要求和锚定板与拉杆的设计方法;并给出了基于悬臂式挡土墙的稳定性分析方法和基于锚定板挡土墙的折线破裂面稳定性分析方法。工程实践表明,给出的计算、分析和设计方法具有较强的应用价值。
The earth retaining wall is a new kind of compound supporting and retaining structure. Taking the double-layer suspended-anchor earth retaining wall as research object, based on the finite element method, the paper studies this kind of retaining wall's design method, and puts forward its calculation method,which is based on Rankine active earth pressure, gives the design demand of wall structure, presents the method of designing anchor plate and drawbar, delivers the stability analysis method toward cantilever retaining wall and polygonal fracture plane stability analysis method. An example results show that this method can be widely used in engineering design. 6 figs, 6 refs.
