摘　　要：文章以哈尔滨市某公寓楼深基坑钢板桩支护项目为研究对象,介绍了基坑钢板桩的选择以及支护方式。应用有限元软件对支护水平位移、基坑四周地表沉降位移以及基坑既有道路位移变化进行了分析。研究发现支护结构最大水平位移为12.8mm,四周地表最大沉降为7.46mm,既有道路最大沉降为8.4mm。由于沥青与混凝土路基路面的材料特性存在显著差异,在受到外部环境因素影响时,应力往往会在两者交汇区域局部显著增强,从而引发应力集中问题。Taking the steel sheet pile support project of the deep foundation pit of an apartment building in Harbin as the research object,this paper introduces the selection of steel sheet piles for the foundation pit and the support methods.The finite element software was applied to analyze the horizontal displacement of the suppor t,the sur face set t lement displacement around the foundation pit and the displacement changes of the existing roads in the foundation pit.The research found that the maximum horizontal displacement of the support structure is 12.8mm,the maximum surface settlement around the foundation pit is 7.46mm,and the maximum settlement of the existing roads is 8.4mm.
