| 摘 要： | 结合具体工程实例,利用ABAQUS软件建立格形钢板桩结构稳定性分析的三维弹塑性有限元模型,分析比较不同土质内和不同入土深度情况下格形钢板桩结构的极限承载力。分析结果表明,土质变化对结构极限承载力的影响很大,经过地基置换后结构的极限承载力显著提高;当基底为淤泥层时,增加结构的入土深度对提高格形钢板桩结构的极限承载力影响有限。

| Abstract: | By combining with some project example, a 3D elastic-plasticity finite element model is created to analyze the structural stability of celled steel sheet pile by ABAQUS software. Analysis and comparison are made for the ultimate bearing capacity of celled steel sheet pile within different soil properties and at different strata depths. It is shown that the ultimate bearing capacity is greatly affected by different soil properties, and significantly improved by the replacement of ground base. However, the ultimate bearing capacity could not be affected much even though the celled steel sheet piles were driven deeper into silt substratum. |
