摘要
合理法(推理公式法)作为国内外流行的水文计算方法被广泛使用,为此,结合案例介绍了基于合理法的设计降雨过程线和径流过程线推求方法,并在此基础上给出了规划阶段暴雨调节塘规模的计算方法,该方法的关键在于径流系数、集水时间、规划径流排放峰值流量限值的合理确定,后续可基于实测数据对方法的可靠性进行验证。该方法有利于合理法的进一步推广应用,可为排水防涝、海绵城市专项规划中暴雨调节塘规模的合理确定提供借鉴。
Rational method is widely used as one of the most popular hydrological calculation methods.A deducing method of the hyetograph and hydrograph was introduced with a case based on rational method,and a calculation method of stormwater detention basin volume in urban planning stage was proposed.The key of the method depended on the reasonable determination of runoff coefficient,concentration time and the discharge limit value of the planned runoff peak flow rate,and the reliability of the method could be verified based on the measured data.The method is conducive to further promotion and application of the rational method,and can provide a reference for the reasonable determination of stormwater detention basin volume in drainage and flood mitigation planning and sponge city planning.
