摘　　要：通过分析长江官洲河段近期河势变化趋势,受上游河势变化影响,幸福洲岸坡崩塌后退,需实施整治工程。为解决幸福洲崩岸问题,对崩岸段采取岸坡防护加固措施。工程实施后,结合新近护岸测图分析幸福洲护岸工程实施后的效果,表明护岸工程的实施保障了岸坡的稳定,历经多次洪水考验,护岸段近岸河床及岸坡相对稳定,护岸效果较好。结合工程实践经验,提出后续建议和保护措施。By analyzing the recent river regime change trend of Guanzhou River Section of the Yangtze River,it is found that the bank slope of Xingfu Sandbar collapses and recedes due to the upstream river regime change,so the regulation works need to be carried out.To solve the problem of bank collapse in Xingfu Sandbar,bank slope protection and reinforcement measures are adopted for the bank collapse section.After the implementation of the project,this paper analyzed the effect of the Xingfu Sandbar revetment project after the implementation in combination with the new bank protection mapping.The results indicate that the implementation of bank protection works guarantees the stability of bank slope.After many flood tests,the nearshore riverbed and bank slope of revetment section are relatively stable and the revetment effect is good.Combining with engineering practice experience,the following suggestions and protective measures are put forward.
