桩板墙在深路堑中的应用分析与优化设计
Analysis and Optimization Design of Pile Slab Wall on Deep Cut

随着社会的发展，铁路，公路领域工程建设中，出现了一些深路堑工程。在深路堑工程中由于挖方的原因会导致初始地应力的重新分布，使得原有的地应力平衡被打破，由此应发了一系列的工程边坡稳定性问题，所以在工程中选择合适的只当结构至关重要。本文采用Midas GTS有限元软件对某深路堑桩板墙进行数值模拟受力分析，并且对比研究在不同工况下的桩板墙，进行优化设计。最终得到其受力特性，选择桩身20 m，截面尺寸2 × 2.5 m，桩间距6 m作为最优方案。
With the development of society, some deep cutting projects have appeared in the construction of railway and highway projects. In deep cutting engineering, excavation will lead to the redistribution of initial ground stress and break the original ground stress balance, thus causing a series of stability problems of engineering slope. Therefore, it is very important to choose the proper structure in the engineering. In this paper, Midas GTS finite element software is used to carry out numerical simulation stress analysis on a pile slab wall in a deep cutting, and a comparative study is conducted on the pile slab wall under different working conditions to optimize the design. Finally, its stress characteristics are obtained. The optimal scheme is 20 m pile, 2 × 2.5 m section size and 6 m pile spacing.
