为推求城区排水排涝体系设计降雨,综合城区排水排涝体系各相关单位要求,在分析城区排水与排涝相关设计降雨规范基础上,探索了推求城区内涝综合设计降雨方法。实例表明,综合设计降雨及排涝流量推算可客观地将城区排涝与排水设计联系起来,满足综合设计要求。研究可为城区防洪排水与排涝体系评估及优化设计提供决策依据。
In order to deduce the rainfall design of urban drainage and drainage system and synthesize the requirements of relevant units of urban drainage and drainage system, based on the analysis of the design rainfall standard related to drainage and drainage in urban area, this paper explores the method of deducing the comprehensive design rainfall of urban waterlogging. The example shows that the integrated design of rainfall and drainage flow calculation can objectively link urban drainage and drainage design to meet the comprehensive design requirements. The research can provide decision-making basis for the assessment and optimization design of urban flood control drainage and drainage system.
