摘要: 用有限元分析方法对筒形基础负压沉贯渗流场进行了动态模拟,提出了筒形基础负压沉贯阻力的数值计算方法;修正了计算筒形基础负压沉贯阻力的公式,并给出了有关系数的取值范围。计算结果表明了计算方法的可靠性和工程实用性。Abstract: A finite element analysis method is applied to the dynamic simulation of the seepage field of suction penetration of bucket foundation platform. A numerical method to calculate the penetrating resistance of bucket foundation is suggested. The formule to calculate penetrating resistance of bucket foundation is meliorated and the range of related factors is also suggested. The resalt indicates that the method suggested is appropriate and practicable for engineering practice.
