摘要
以山东省某市新城区为例,运用暴雨管理模型(SWMM)对新城区雨水排放系统进行模拟。为有效解决城市内涝问题,更加贴近海绵城市理念,同时对连续降雨下城市的雨洪实现最大化下渗,在模拟城市雨水管道系统的基础上增加LID控制,并对管道断面进行优化改造。最终结果表明在重现期P为1.5、3、10 a的条件下的圆形、矩形、复合断面(倒凸性)的排水断面管道中,重现期较小时3种断面形式过流能力相近;重现期较大时,矩形管渠为优先选择对象。
This paper uses the new district of Shandong Province as an example, the storm water management model （SWMM） of the new urban drainage system is simulated. To effectively solve the problem of city waterlogging, LID control is strengthened based on the simulation of city water pipeline system on the cross section and transformation is optimized. The results show that in a period of P= 1.5,3,10 a under the condition of circular, rectangular, composite section （inverted convexity） of the drainage section in the pipeline, the return period is three hours off surface flow capacity.
