摘　　要：北京市作为严重缺水城市,如何有效利用水资源成为了社会各界关注的焦点问题。同时,雨水的收集与利用作为城市水土保持工作研究的重要课题,正逐渐被人们关注。针对目前北京市房地产建设项目地表雨水入渗与收集的情况,介绍了渗沟这一城市水土保持雨水收集与利用措施,详细分析渗沟措施设计要点及入渗能力。通过对北京市具体案例的分析,阐述了渗沟措施典型设计对雨水收集及地表水入渗的能力,提出了渗沟设计对地表雨水收集所起到的重要作用,希望对城市中水土保持渗沟措施的设计具有参考意义。Beijing is a c focus problem concerned ity suffering from serious water shortage, how to use water resources efficiently is a by social public. Meanwhile, the collection and utilization of rain water is also an important subject in the work of urban soil and water conservation, which is gradually concerned by the public.According to the characteristic of infiltration and collection of surface rain water in Beijing real estate project, infiltration trench is introduced in this paper as one of effective measures of rain water collection and utilization, in addition, design points of infiltration trench and its infiltrationcapacity are analyzed in detail. Based on cases study, typical design of infiltration trench is illustrated, and the effect of infiltration trench on the infiltration and collection of surface rain water is analyzed as well. It improves that infiltration trench has an important function for surface rain water collection, which could be a good reference to the measure design of urban soil and water conservation.
