摘　　要：通过分析长江上下三号河段近期河势变化趋势,由于受上游河势变化影响,王家洲岸坡易发生崩塌后退,需实施整治工程。为解决王家洲崩岸问题,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,对该区域水文和地质进行了研究,分析了河道演变,并采用了平面法、横断面法和冲淤分析法,综合分析王家洲护岸工程实施后的效果。结果表明:护岸工程的实施保障了岸坡的稳定,历经多次洪水考验。实际说明护岸段近岸河床及岸坡相对稳定,护岸效果较好,并结合工程实践经验,提出后续建议和保护措施。By analyzing the recent change trend of river regime in the upstream and downstream Sanhao reaches of the Yangtze River,it is found that due to the influence of changes in upstream river regime,the bank slope of Wangjiazhou is prone to collapse and retreat,which requires the implementation of rectification projects.In order to solve the problem of bank collapse in Wangjiazhou,the protection and reinforcement measures of bank slopes have been taken for bank collapse reaches.After the implementation of the project,combined with recent bank protection mapping,the hydrology and geology of this area are studied,the evolution of the river channel is analyzed,and the plane method,cross-sectional method and erosion and deposition analysis method are used to comprehensively analyze the effect of the implementation of the bank protection project in Wangjiazhou.The results indicate that the implementation of the revetment project ensures the stability of bank slopes,and that they have been tested by multiple floods,which actually shows that the nearshore riverbed and bank slope of revetment reachs are relatively stable with good revetment effects.Combined with the practical experience of the project,follow-up suggestions and protection measures are proposed.
