摘要
结合工程实际情况,采用一维水动力模型对河道水面线进行推求计算,为河道治理工程设计提供参考。选取常见的3种护岸形式进行比选,3种方案在工程中均具有一定的适宜性,可根据实际情况分段选取。为打造良好的亲水环境,采用100 mm厚防渗混凝土、砂卵石保护层防渗结构进行河底防渗。通过对典型断面的挡墙进行稳定性复核,挡墙可满足稳定性要求。
Based on the actual situation of the project,a one-dimensional hydrodynamic model is used to calculate the water surface profile of the river channel,which can provide reference for the design of river regulation project design.Three common types of revetment are selected for comparison.All three schemes have certain applicability in the project and can be selected according to the actual situation.In order to create a good hydrophilic environment,the seepage prevention structure of a 100mm thick impervious concrete and sandy gravel protective layer is used for the river bottom.Through the stability review of the retaining wall of the typical section,the retaining wall can meet the stability requirements.
