【摘要】 随着我国城市雨洪利用工程的快速发展,关于雨水池设计理论及计算也有了较多的探讨和研究,但仍需进一步完善。针对雨水池设计现状,以及半干旱地区的降雨情况,通过对天津市日降雨量的分析,建立了日降雨—用水平衡模型。利用计算机编程计算出不同用水需求条件下,城市小区雨水蓄水池的合理规模。该模型可为雨水池修建提供设计依据,同时也可为源头污染控制以及雨水洪峰调蓄提供数据支持。更多还原

【Abstract】 With the accelerated development of urban rainwater utilization in China,theoretical design and calculation of rain tanks have been studied and reported widely.However,improvements are still required to realize efficient rainwater collection and utilization.Based on current design of rain tanks and rainfall characteristics of semi-arid area,a daily rainfall-water usage balance model was established by analyzing of daily rainfall in Tianjin City.A reasonable volume of rainwater tanks calculated by a computer program with respect to different water usage conditions.This balance model not only provides a design basis for rain water tank deployment,but also plays an important role for source pollution control and flood peak adjustment.更多还原
