摘要
防波堤的稳定性和消波特性是直接反映防波堤工程质量和使用功能的重要指标。在传统的防波堤设计理念中,堤身出现滑移就意味着防波堤结构的破坏,而当今防波堤设计的1种新思路是在保证防波堤整体结构不发生破坏的情况下,允许堤身存在一定的滑移量。重点介绍防波堤稳定性和消波特性研究方面的进展,探讨堤身滑移对防波堤稳定性的影响,建议在外海和软弱基础地区采用半圆形防波堤。
The stability and wave absorbing characteristic of breakwater are two important indexes,which reflect the quality and function of the breakwater project directly.Breakwater slipping represents the breakage of structure in the conventional design concept of breakwater.But in current breakwater design,as a new design option,certain slippage is permitted subject to the integral breakwater structure being guaranteed.The research progresses on the stability and wave absorbing characteristic of some breakwaters are introduced as important issues.The influence of breakwater slipping on its stability is discussed.The semi-circular breakwater is suggested for open sea and soft foundation area.
