| 摘 要： | 利用有限元数值计算方法模拟筒型基础负压沉贯过程中的渗流场。结果表明:在筒型基础裙端部的渗流场比较复杂,特别是裙端部的渗流速度最大;筒型基础内土体表面渗出速度随筒型基础入土深度增加而分布均匀,同时筒型基础内土体表面渗出速度或渗入速度随筒型基础入土深度的增加而减小。此结果与实践和试验符合良好。

| Abstract: | The paper uses FEM to simulate the seepage velocity field for the suction assisted penetrate caissons. The simulation results support the conclusion that the biggest seepage velocity takes place near the shirts of caissons, the permeability velocity is uniform in caissons, and seepage velocity declines as the penetrating of caissons. Those consist with relative experiences. |
