基于SWMM的雨水调蓄池容积研究

摘要

Rainwater storage pool is an important measure for urban inland inundation prevention and treat﹣ment, therefore, the confirmation of its effective volume plays significant role in the engineering design. Take a city in Yunnan province as example, the results of effective volumes calculated by two different methods: tradi﹣tional formula mthod and SWMM software simulation, were compared and analyzed, it was indicated that, under the low recurrence interval, the calculated value by formula method was superior to that calculated by software simulation;however, under high recurrence interval, the results was on the contrary.%雨水调蓄池作为城市内涝防治的一种重要措施,其有效容积的确定在设计过程中极为重要.以云南省某市为例,采用传统公式法计算与SWMM软件模拟2种方法得到调蓄池有效容积,对2种方法的结果进行比较分析,结果表明在低重现期下公式法计算值要大于软件模拟值,而在高重现期下软件模拟值将大于公式计算值.
