悬臂式板桩入土深度的ANSYS数值模拟

ANSYS Numerical Simulation in the Insert Depth of Cantilevered Sheet Pile

板桩作为一种挡土支护结构,常用在码头、船闸以及基坑开挖等工程中,因此存在一个板桩入土深度的设计问题。现有的计算方法不考虑墙与土之间的实际变形情况和其对土压力的大小与分布的影响,存在一些不可忽视的缺陷。采用ANSYS有限元软件对悬臂式板桩进行了三维实体数值模拟,得到了板桩位移,并分析得出其入土深度,计算结果符合实际情况,这为悬臂式板桩结构入土深度的设计校核提供了可靠的参考数据。

As a kind of soil retaining support structure, sheet pile commonly used in the dock, lock and founda- tion pit excavation projects, thus, there exists a sheet pile soil into depth design problem. The existing calculation method does not consider the wall between soil and the actual deformation condition and the earth pressure of the influence of size and distribution software are used in the numeric , there are some defects can not be neglected. In this paper, ANSYS finite element al simulation of 3-d entity of the cantilevered sheet pile. Get the sheet pile dis- placement, and analysis the insert depth, the calculation results tally with the actual situation. This can provide the reliable reference data for designing and checking the insert depth of the cantilevered sheet pile structure.
