摘　　要：根据浙江滨海地区某电厂厂区的工程地质情况,以海相沉积软土地基基础施工阶段的现场沉降监测数据为基础,将软基沉降曲线分为3种形态。探讨了硬壳层、软基厚度、堆载高度及堆载速率等因素对沉降曲线的影响,分析了海相沉积软土地基的沉降变形规律,为滨海地区软基加固工程施工提供参考。According to the engineering geological condition of a power plant located in the coastal area of Zhejiang Province, the settlement curve of the marine sediment foundation therein is divided into three patterns based on the in situ settlement monitoring data during the construction. The impacts from the factors such as the hard-shell layer, the thickness of the soft foundation, the height of the surcharge load, the rate of the surcharge loading, etc. are discussed herein, and then the settlement deformation law of the soft marine sediment foundation is analyzed as well, so as to provide a reference for the relevant soft foundation reinforce- ment nroiect in coastal area.
