摘　　要：文章依托常州地铁2号线青枫公园站基坑开挖工程,利用室内土工实验获取了常州市区小应变土体硬化本构模型的土层参数,同时运用了有限元分析软件,对该深基坑的施工过程进行了数值模拟,将数值模拟获得的土体位移及支护结构变形的计算结果与现场监测成果进行对比分析,检验了常州地区小应变硬化土体模型参数的有效性,研究成果对常州地区后续的基坑工程具有一定的参照意义。In this paper, based on the excavation project of qingfeng Park Station of Changzhou Metro Line 2,the soil parameters of the small strain soil hardening constitutive model in Changzhou urban area were obtained by indoor geotechnical experiment, and the construction process of the deep foundation pit was numerically simulated by using finite element analysis software. The soil displacement and supporting structure deformation calculated by numerical simulation are compared with the field monitoring results, and the validity of the soil model parameters of small strain hardening in Changzhou area is verified. The research results have certain reference significance for the subsequent foundation pit engineering in Changzhou area.
