长江江苏河段嘶马弯道崩岸与护岸研究

在总结前人研究的基础上，对长江江苏河段把弯道来水来沙，河床边界组成，弯道横向环流情况下的水沙运动和河床演变进行了分析，探讨了嘶马弯道崩岸坍江的原因，特点和工程防护措施，对弯道的稳定性运用钱宁公式进行了计算分析研究。结合嘶马河段护岸工程实践，对丁坝，沉排，平顺抛石等护岸形式进行总结比较，探求最佳护岸类型，进一步对长江扬中河段特别是嘶马弯道作出系统的整治规则。

Bank Caving and Protection at Sima Bend of Jiangsu Section of Yangtze River

Based on a summary of previous researches, analyzed are coming water and sand into the Sima bend, components of the river bed boundary, and water and sand movement and river bed deformation under transverse circulation. The causes and characteristics of bank caving and engineering protection measures are discussed, and the stability of the Sima bend is calculated and analyzed by use of the QianNing formula. In combination with the Sima bank protection project, some bank protection measures, such as construction of spur dikes, sinking mattress, and smooth rock riprap, are compared for search of the optimum measures. Finally, a general plan is proposed for the regulation of the Yangzhong reach of the Yangtze River.
