西安站北广场项目雨水排放及防涝措施

Rainwater drainage and waterlogging prevention measures for the North square project of Xi’an railway station

根据项目特点,介绍了雨水排放系统设计中不同区域重现期和径流系数确定的原则、广场硬质铺装和绿化地面防积水和防渗漏迅速排水的措施,提出了一种超设计重现期下沉区域雨水防涝措施设计的新思路。

Based on the characteristics of the project,this paper introduces the principles of the determination of the reproduction period and runoff coefficient of different areas in the design of the rainwater drainage system,the measures of the square hard paving and greening the ground to prevent water accumulation and rapid drainage of leakage,and puts forward a new idea for the design of rainwater flood prevention measures in the subsurface area during the super-design reproduction period.
