摘　　要：单排桩挡墙作为永久支挡结构的应用逐渐增多,但针对其受力和变形特性的研究相对较少。本文依托深圳某地铁停车场边坡支护工程,通过理正岩土和Midas GTS NX有限元软件分别建模计算并与现场实测数据对比分析。结果表明采用理正岩土软件计算得到的桩身弯矩、剪力及变形沿桩身的变化规律与有限元分析结果基本一致。两种计算方式得到的桩顶水平位移量与现场实测结果相近。研究成果对于永久单排桩挡墙支挡结构的设计和检算具有较高的指导意义。The application of single-row pile retaining structure at permanent retaining engineering is gradually increasing,but the research on its stress and deformation characteristics is relatively few.This paper was based on an engineering example at a subway parking lot in Shenzhen.Through the modeling and calculation of Lizheng geotechnical software and Midas gtsnx finite element software,the analysis and comparisons between model calculation results and field measured data were completed.The results show that,the variation laws of pile bending moment,shear force and deformation along the pile body are basically consistent between Lizheng geotechnical results and finite element analysis.Horizontal displacements of the pile top obtained by previous calculation methods were close to the field measured datas.The research results have high guiding significance for the design and checking of permanent single-row pile retaining structure.
