结合东濠涌流域的排水现状和深层隧道排水工程方案,利用Info Works ICM软件构建河道、排水管渠和深层排水隧道系统的综合水力模型,研究了建设深隧前后的截污系统溢流次数和污染物削减率,讨论了系统管渠的排水标准和水浸风险等级,对比了河涌水面线和防洪标准,结果表明,深层排水隧道的建设可有效提高城市防洪和水污染控制标准。
According to the drainage status of Donghurong River Basin and the scheme of deep tunnel drainage project, Info Works ICM software is used to construct comprehensive hydraulic model of river channel, drainage canal and deep drainage tunnel system. The number of overflow and Pollutant reduction rate. The drainage standards and the risk level of flooding were discussed. The creek water surface line and flood control standard were compared. The results show that the construction of deep drainage tunnel can effectively improve urban flood control and water pollution control standards.
