摘要
在满足径流控制率等规划指标的条件下,建筑小区海绵改造时可以采用多种LID技术方案,对这些方案如何取舍,设计师往往具有很大的随意性。提出设计前先对小区进行现场观测,并对拟采用的SWMM模型参数进行率定,然后结合不同暴雨重现期的SWMM模拟结果。考虑规划地块水文特性改善、工程造价、环境效益等多因素,利用模糊综合评价方法对LID组合方案综合效益进行评价,最终找出最佳LID工程组合方案。该方法可以为低影响开发技术的应用提供借鉴。
Under the condition of meeting the planning indexes such as runoff control rate,many kinds of LID technical schemes can be adopted in the sponge reconstruction of residential area.Designers often have a lot of discretion about how to choose between these schemes.It is proposed that the field observation is carried out for a residential area before design,the parameters of SWMM model to be adopted are calibrated,and then the results are simulated in combination with the different rainstorm recurrence periods of SWMM.By considering the factors of the hydrological characteristics improvement,engineering cost and environmental benefits of the planned land,the comprehensive benefits of LID combination scheme are evaluated by using the fuzzy synthetic evaluation method.Finally,the best LID engineering combination scheme is found out.This method can provide the reference for the application of low-impact development technology.
