摘要
为解决城市内涝、缺水和水污染问题,结合工程所在区域的自然地理条件与现有低影响开发设施,提出了适用于岳阳市得胜北路海绵城市建设的整体规划方案。收集岳阳市近30 a的降雨资料,对岳阳市暴雨强度公式进行改进,并对年径流总量控制率进行评价和分析。研究结果表明:改进后的暴雨强度公式计算值与实测值之间相对误差的绝对值大部分小于5%;实体工程下沉式绿地的实际调蓄容积满足岳阳市海绵城市建设设计调蓄容积的要求;海绵城市系统可促进雨水下渗及在干旱时存储雨水,发挥“渗水”与“储水”功能。
In order to solve the problems of urban waterlogging,water shortage and water pollution,combined with the natural geographical conditions and the existing low-impact development facilities of the project area,the overall plan scheme for the sponge city construction of Desheng North Road in Yueyang City was proposed.Collecting rainfall data of Yueyang City in recent 30 a,the rainstorm intensity formula of Yueyang City was improved,and the total annual runoff control rate was evaluated and analyzed.The research results show that the absolute values of the relative errors between the values calculated by the improved rainstorm intensity formula and the measured values are mostly less than 5%.The actual storage volume of the sinking green space of the physical project meets the requirement of design storage volume for Yueyang City sponge city construction.The system can promote the rainwater infiltration and store rainwater during drought,performing the functions of"water seepage"and"water storage".
