按水力学观点仔细分析了密排桩防波堤,检验了波浪穿透此种防波堤的各理论。介绍一处由单排八角桩组成的双臂式防波堤的实况研究。该防波堤是为一驳船码头在西南季节风时取得防护而修建的。对该防波堤的波浪传递系数及波压力作了分析,并对理论计算得出的传递系数及单桩上的波压力值与模型试验所得到的结果进行了比较。
According to the hydraulics point of view, the breakwater of densely packed piles was carefully analyzed and the theories of wave penetration through such breakwater were tested. A case study of double arm breakwater consisting of single octagonal pile is introduced. The breakwater was constructed to provide protection for a barge pier during the southwestern seasonal winds. The wave transfer coefficient and wave pressure of the breakwater are analyzed. The theoretical transfer coefficient and the wave pressure on the single pile are compared with those obtained by the model test.
