【摘要】 本文提出了一种新型支挡结构形式—悬锚式挡土墙。通过室内三轴试验，运用邓肯—张非线性有限元模型，得到有限元计算所需参数；分析了悬锚式挡土墙所受的土压力的分布规律及大小；通过改变有限元模型参数，经有限元计算，确定该结构的建筑高度；利用梁单元对挡墙结构进行比较分析，确定悬锚式挡土墙的设计计算方法。通过所得的结论，提出悬锚式挡土墙的施工工艺，并对施工中的重要环节作出要求。更多还原

【Abstract】 In this paper, a new kind of retaining that is called cantilever-anchor retaining isbrought out. Through the triaxial test in the laboratory and the Duncan-Chang model,the parameters used in the finite element model were confirmed. The distributing lawand magnitude of the soil pressure on the retaining are analyzed; Through calculatingthe finite element model with different parameters, the structure’s highness is gotten,Through comparing and analyzing different retaining with grider element method, thedesign method of the camilever-anchor retaining is advanced. According to theconclusions, the construction method of the cantilever-anchor retaining is brought out,at the same time, the paPer brings out the request to the important steps in theconstruction.更多还原
