收集了苏州地铁一号线23座车站深基坑的详细监测资料,在对大量实测数据统计分析的基础上,系统分析了苏州地铁一号线深基坑的变形特性;给出了三种典型围护结构-地连墙、咬合桩和SMW围护桩的侧移、墙后地表沉降变化范围及平均值,并与其他地区的统计数据进行了比较;并进一步分析了软弱土层厚度、墙体入土深度对基坑变形的影响。分析得到的若干规律性结果,可为本地区后续地铁工程的建设提供参考。
Based on the statistical analysis of a large number of measured data, the deformation characteristics of deep foundation pit of Suzhou Metro Line 1 are systematically analyzed. Three typical The range and average value of the surface settlement of the retaining structure - ground retaining wall, bite piles and SMW retaining piles, and the surface settlement after the wall were compared with those of other areas. The thickness of soft soil and the wall Influence of soil penetration depth on deformation of foundation pit. The analysis of some regularity results can provide references for the follow-up metro project construction in this area.
