以1延米长的护坡工程量为计算基础，结合已建工程建设经验和年楚河实际情况，对浆砌石毛石、铅丝笼干砌石和部分预制混凝土块3种护坡方案进行了比较分析，确定铅丝笼干砌石为最优设计方案，然后对铅丝笼干砌石进行了指标设计，并对堤岸的冲刷深度、抗冲刷和护坡稳定性进行了分析计算，最后对实施效果进行了分析。设计方案实施后不仅满足了护坡安全的规范设计要求，而且节省了投资，防洪效益明显。%The paper calculated on the basis of 1 linear meter’s project amount of revetment,combined of built engineering experience and local conditions,analyzed three slope protection program. The gabion dry stone was optimal design. Next,the indicators were designed of gabion dry stone pitching,and scour depth,anti-erosion and slope stability were calculated of the embankment. Last,the implementation effect was analyzed. The results show that the design not only meets the design specification for revetment safety,but also saves the investment,its flood control benefits are immeasurable.
