摘要
作为一种板桩墙结构形式,主桩套板结构的受力情况比较复杂,当套板相对变形较大时将产生土拱效应。在介绍土拱形成原理的基础上,利用ABAQUS软件建立主桩套板结构的平面应变模型,重点研究结构尺寸和土体性质对土拱效应的影响,结果表明前者影响较大,后者的影响相对较小。在对主桩套板结构进行设计时,为充分发挥土拱效应降低工程造价,可在一定范围内适当增加主桩净距、减小套板厚度。
The main pile with inlaid sheet structure is a type of sheet-pile wall with complicated force conditions. When the deformation of inlaid sheet increases, it will produce soil arching effect on the structure＇s back side. Based on the introduction of soil arching theory, we build a plane strain model by ABAQUS software to study the impact of structure size and soil properties on soil arching effect. The results indicate that the structure size has a greater contribution to the effect. To a certain extent, the effect of soil properties is relatively small. In the design of main pile with inlaid sheet structure, in order to give full play to the soil arching effect and save project cost, main pile interval could be increased appropriately, and inlaid sheet thickness should be reduced within a certain scope.
