城市道路路面行泄通道设计标准的确定方法研究

Research on mothods to determine design standards for excess stormwater pathway of urban road

设计标准是开展城市道路路面行泄通道设计的前提和核心,直接影响路面行泄通道的全面推广实践.鉴于现阶段确定路面行泄通道设计标准的综合性和复杂性,提出两种相对简易的方法,即设计流量法和设计重现期法,用以确定路面行泄通道的设计标准,并通过实际案例验证两种方法的可行性.

Design standard is the premise and core of excess stormwater pathway design,which directly affects the comprehensive promotion and practice of excess stormwater pathway.In view of the comprehensiveness and complexity of determining design standards of excess stormwater pathway at this stage,this paper shows two relatively simple methods,namely,flowrate mothod and Recurrence interval method,to determine design standards of excess stormwater pathway,and verifies the feasibility of the two methods through practical cases.
