城区雨水渗透设施计算方法及关键系数

Calculation and the Key Parameter in Urban Storm Water Infiltration Design

常用的城区雨水渗透设施计算方法有图解法和Geiger法等。在对其安全性、准确性分析的基础上 ,认为北京地区应推荐使用图解法。并对计算关键系数———渗透系数的确定提出了建议。

Graphic and Geiger calculation methods are common used in urban storm water infiltration design. On the basis of safety and accuracy analysis the authors recommend the graphic method for Beijing area and suggest practical advice to ascertain the infiltration coefficient, a key parameter in the calculation. Finally explains are given by a practical project.
