【摘要】：应对新一轮的发展契机,国家重提城镇化战略。但快速的城镇化不仅带来巨大的人口和财富集聚,也在空间上促使雨洪径流集聚,从而造成了严重威胁城市安全的雨洪灾害。在发展新型安全城市的背景下,以雨洪资源丰富且内涝现象频发的杭州市为例,试图在以往被认为是单一的城市排水领域中,结合利用城市规划的思想和技术方法,提出新型城市雨洪控制的规划研究。本文关注城市雨洪从自然降水、地表汇集和城市排水全过程中产生的可能性,通过分析杭州市自然降水特征、地表下垫面评价、规划用地及开发强度与雨洪径流之间的变化关系,认为洪涝的主要成因是雨洪的时空分布矛盾。从雨洪控制系统构成出发,具体分析了杭州市发展雨洪控制规划的技术可行性、建设可行性和推广可行性。指出有效控制雨洪的关键在于区别对待不同成因、来源、质量的雨洪,将雨洪作为城市安全设计的重要因子,从宏观到微观将雨洪控制结合城市规划编制,根据杭州实际情况研究不同规划用地的雨洪控制目标和配置设施建议,提出合适的雨洪系统工程政策、工程建议及发展趋势。
[Abstract]:Response to a new round of development opportunities, the country again proposed urbanization strategy.However, rapid urbanization not only brings huge population and wealth accumulation, but also promotes rainwater runoff accumulation in space, thus causing a serious threat to the safety of the city.In the context of developing a new safe city, taking Hangzhou City, which has abundant rain and flood resources and frequent waterlogging phenomenon, as an example, this paper attempts to combine the ideas and technical methods of urban planning in the field of urban drainage, which was considered to be a single city in the past.A new type of urban rain flood control planning is proposed.This paper focuses on the possibility of urban rain flood from the whole process of natural precipitation, surface collection and urban drainage. By analyzing the characteristics of natural precipitation in Hangzhou, the evaluation of surface underlying surface is made.It is considered that the main cause of flood is the contradiction of temporal and spatial distribution of rain flood.Based on the composition of rain flood control system, the technical feasibility, construction feasibility and popularization feasibility of developing rain flood control planning in Hangzhou are analyzed in detail.It is pointed out that the key to effectively control rain flood is to distinguish between different causes, sources and quality of rain flood, to take rain flood as an important factor of urban safety design, and to combine rain flood control with urban planning from macro to micro.According to the actual situation of Hangzhou, the paper studies the rain flood control objectives and facilities of different planning land, and puts forward the appropriate project policy, engineering suggestion and development trend of rain flood system.
