摘要： 结合武汉某地铁深基坑工程的地质条件、支护结构设计、实际施工工序等，通过现场监测数据，分析围护桩的深层水平位移、支撑轴力、立柱沉降、地表沉降等的变化规律，分析不同位置和不同工况数据的原因和主要影响因素，并对比施工监测数据和理正深基坑设计软件建模计算结果，分析表明软件计算与现场监测结果较为一致，并得到基坑围护结构变形和受力情况受基坑尺寸、施工工况和桩体嵌固深度的影响。

Abstract: The case history of the monitoring of a metro station excavation supporting system in Wuhan is presented in this paper. The subsurface conditions, structural design, and the construction sequences for the station excavation are discussed. Throughout the monitoring data, the lateral deflection values of the soldier piles at different layers, axial forces in the inclined and vertical struts as well as ground subsidence values were compared with the analytical results. Factors that affecting the performance of the supporting system were evaluated. The results indicate that the stress and deformation of the supporting system are influenced by the dimensions of area to be excavated, construction conditions and embedment depths of soldier piles.
