摘　　要：作用在直墙上的近破波对建筑物具有极大的破坏力,其作用机理非常复杂,至今尚无统一认识。利用粒子图像测速(PIV)技术与高精度压力传感器对直墙前的近破波流场和破波压力进行了同步测试,通过流场结构与破波压力的同步对比分析,探讨了近破波对直立建筑物的作用机理。Breaking wave has a tremendous destructive power to the vertical-wall structures located on bedding.Up to now,the mechanism of breaking wave has not been found out.By using PIV technology and highprecision pressure transducers,this paper studies the breaking wave＇s flow field and wave pressure.The mechanism of breaking wave force impacting on the vertical-wall structure is discussed in contrast to the flow field and wave pressure.
