摘　　要：波浪作用于直墙上会造成水体的强烈紊动,从而对直立堤的明基床及其前面的海床产生淘刷作用,尤其对于处在深水区、受大浪作用同时产生立波的情况下,破坏作用更明显。为避免波浪的运动对直墙结构带来严重的后果,直立堤前设置稳固的防冲刷设施是非常必要的。文中所述意大利某项目的深水明基床直立堤,通过中外不同规范、手册对抛石基床护面块体重量进行计算对比,并依次采用物模试验进行验证,提出该项目的深水直立堤在大浪作用下抛石基床护面重量采用预制混凝土护肩块体设计较为合适,本文分析成果可为类似工程项目提供一定的参考。Waves acting on a vertical dike will cause severe turbulence of water body,which may scour the exposed foundation bed of the vertical dike and the seabed,and result in more obvious destruction under the combination of standing waves and strong waves in deep-water area.In order to prevent the vertical dike from wave movement,it is necessary to set stable anti-scouring facilities in front of the vertical dike.Based on an Italian deep-water vertical dike with exposed foundation bed,by comparing the calculation methods for the weight of armor block of rubble mound foundation specified in different standards and manuals at home and abroad,the physical model tests show that the foot protection blocks made of pre-fabricated concrete are applicable for the deep-water vertical dike under the condition of strong wave.The analysis results will provide a certain reference for similar projects.
