【摘要】 钱塘江涌潮压力的作用性状及大小一直是困扰工程界的一个难题。本文采用VOF方法,对涌潮冲击丁坝过程中的涌潮压力进行了计算,并与原位测试结果进行对比。从而揭示了涌潮压力的部分规律:(1)涌潮对丁坝的破坏力最大的时刻是在涌潮冲击丁坝的瞬间;(2)涌潮压力随时间的变化规律;(3)涌潮压力在垂线方向上的分布。为排桩式丁坝的设计提出了新型的受力模式。更多还原

【Abstract】 The function character and size of the Qiantangjiang bore pressure is always a problem in engineering.In this paper ,the bore pressure when the tide strikes the groin is calculated by the method of VOF,and is campared with the result of the in situ test.The analysis result shows that: (1)The time that the bore destroy the groin most is when the bore arrivied; (2)The rule of the bore pressure with time;(3)The distribution of the bore pressure along vertical space which is a new type loading mode for the design of pile-groin.更多还原
