摘　　要：目的:本研究旨在分析HUW组合钢板桩在软土地基深基坑工程中的结构适应性,以期为相似地区深基坑工程提供理论支持。方法:基于某软土地区科技产业园深基坑工程,运用ABAQUS有限元软件,通过增量法模拟实际开挖过程,计算正常开挖下的结构变形和土体位移,从而分析HUW组合钢板桩在实际工程中的结构可行性。结果:随着基坑的逐层开挖,基坑边缘的沉降值逐步增大,尤其在软土地基条件下,地表沉降现象更为明显。针对6.3米深基坑的开挖,HUW组合钢板桩的最大水平位移为22.78毫米,符合基坑施工规范的要求。结论:HUW组合钢板桩在实际工程中具备可行性,可为类似工程提供理论参考。但土体受侧向约束的影响,在边界区域会形成局部隆起,因此需对边坡边缘进行加固处理。Purpose:The purpose of this study is to analyze the structural adaptability of HUW combined steel sheet piles in soft soil foundation deep foundation pit project,with a view to providing theoretical support for deep foundation pit projects in similar areas.Methods:Based on the deep foundation pit project of a science and technology industrial park in a soft soil area,ABAQUS finite element software is used to simulate the actual excavation process through the incremental method,and the structural deformation and soil displacement under normal excavation are calculated,so as to analyze the structural feasibility of the HUW composite steel sheet piles in the actual project.Results:With the layer-by-layer excavation of the foundation pit,the settlement value at the edge of the foundation pit increases gradually,especially under the soft ground condition,the surface settlement phenomenon is more obvious.For the excavation of 6.3-meter deep foundation pit,the maximum horizontal displacement of HUW combined steel sheet pile is 22.78 mm,which is in accordance with the requirements of foundation pit construction specification.Conclusion:HUW combined steel sheet pile has feasibility in actual project and can provide theoretical reference for similar projects.However,the soil body is affected by lateral constraint,and local bulging will be formed in the boundary area,so it is necessary to reinforce the edge of the slope.
