【摘要】 通过分析D河道流域地块开发前后的不同排水标准,计算出D河道在地块开发前后的设计流量,通过流量分析,提出对D河道断面改造方案,并通过水力模型分析,改造后的D河道满足片区排水要求。D河道的排水改造设计中还包含了生态挡土墙设计及绿化景观设计。更多还原

【Abstract】 This paper calculates the design discharge of D river before and after the development of D River drainage basin by analyzing the different drainage standards before and after the development of D River drainage basin. Through the flow analysis, it puts forward a plan for the reconstruction of D River section. The dimension of D River after the reconstruction is 25 m×3.5 m. Through the hydraulic model analysis, the D River after the reconstruction meets the drainage requirements of the area. The design of drainage improvement of D River also includes the design of ecological retaining wall and the design of greening landscape.更多还原
