摘要
提出了雨水系统设计计算中划分汇水面积的新方法——面积管长比法(亦称“树分法”),即将汇水面积按管长分配的方法。通过绘制汇流等时线图模拟了实际雨水的汇水情形并以此为参照,分析了面积管长比法与传统汇水面积划分法及“汇流等时线法”的异同和优缺点。
A new method--ratio of total area and path length method was presented for dividing the water catchment area in the design of rainwater system. The confluent isochrone was plotted to simulate the actual catchment of water. Based on this, analysis was made on the difference among the ratio of total area and path length method, traditional division method for water catchment area, and ＂confluent isochrone＂, as well as their characteristics.
