河道治理工程堤防选型与稳定性分析

Type Selection and Stability Analysis of Levee in River Regulation Project

为了提高河道的防洪能力,结合河道现状对工程布置情况进行研究。选取3种型式堤防方案进行比选,采用素混凝土重力式挡墙型式占地面积小,作为推荐方案。根据河道水面线推求和安全加高要求,确定堤顶高程,经过稳定性复核分析计算,堤防型式满足安全要求。研究结果可为河道防洪安全提供参考。

In order to improve the flood control capacity of the river channel,the engineering layout is studied based on the current situation of the river channel.Three types of embankment schemes are selected for comparison.The plain concrete gravity retaining wall type is recommended because of its small floorprint.According to the calculation of river water surface profile and safety heightening requirements,the embankment top elevation is determined.After stability review analysis and calculation,the embankment type meets the safety requirements.The results can provide reference for river flood control safety.
