珠海桂山岛十三湾防波堤修复加固方案

针对开敞海域防波堤结构遭遇风浪袭击而破坏的问题,分析破坏原因并选择适用的修复加固方案。引用较为详实的的风、浪、水流等资料,特别考虑了近些年出现的几个强、超强台风对工程海区风浪的影响,通过规范计算与模型试验相结合的方式,确定防波堤堤顶高程、护面块体质量等主要设计参数及断面结构形式。同时,从防波堤使用功能及港内泊稳条件的角度考虑,优化防波堤平面布置。结合模型试验研究成果,提出了针对性较强的修复加固及优化布置方案,对类似工程具有一定的借鉴意义。

Rehabilitation and reinforcement scheme of breakwater in the thirteenth bay of Guishan Island,Zhuhai

Aiming at the damage problem of breakwater structure in open sea area caused by wind and wave,the reason of damage is analyzed and the suitable repairing and reinforcement scheme is selected.Based on the detailed data of wind,wave and current,especially considering the influence of several strong-super typhoons on the wind and wave in the engineering sea area in recent years,the main design parameters such as the top elevation of breakwater,the mass of protective face block and the cross-section structure pattern are determined by combining standard calculation with model test.At the same time,the layout of the breakwater is optimized from the point of view of the function of the breakwater and the berthing conditions in the harbor.Combining with the results of model test,this paper puts forward a more pertinent scheme of repairing and strengthening and optimizing layout,which has a certain reference significance for similar projects.
