摘要
直立式防波堤的波浪荷载除了来自波浪场中的作用力外,还有海床渗流引起的波浪渗流力的作用,后者也是不容忽视的环境因素之一。本文对无限厚度可渗可压缩海床情况,给出了直立式防波堤下海床中波浪渗流压力的封闭形式的解析解,进而可以给出作用在防波堤基底上的浮托力和倾覆力矩。分析中考虑了土介质变形和孔隙水压缩性,渗流压力的控制方程为P=C_8P/t。海底面上的波浪压力采用了线性波浪理论的结果。
An important factor in the design of a breakwater is the action of wave in duced pore-water forces exerted on the base of the structure. In this paper, a closed-form solution to wave induced seepage pressure in infinite-depth seabed is obtained by taking into account the soil deformation and the compressibility of the pore-water. The governing equation for seepage pressure is ▽2P=CxP/t·The sea bottom pressure condition is determined from linear wave theory.
