摘　　要：对软土地层管幕法施工过程进行了三维数值模拟,得到了施工过程中地表沉降和管幕周围土体的位移变化规律,并同实测结果进行了比较。结果表明:采用D-P模型可以在不考虑土体时变特性的情况下较好的模拟管幕法施工过程。Finite-element method was adopted to simulate the construction procession using pipe-curtain method in soft soils, and the rules of displacement of ground and soils around pipe-curtain during construction procession were obtained. The results were compared with the measured data. The comparison showed that D-P model could simulate the construction procession using pipe-curtain method without considering the time-dependent properties of soils.
