摘要
为给深层排水隧道等大口径排水系统规划和工程设计提供计算支撑,基于深隧服务范围内的七个雨量站的分钟降雨资料,采用垂直平分法(泰森多边形法),对降雨点面折减系数进行推求,并结合国内外相关研究成果对点面折减系数进行分析,得出了满足广州市中心城区深隧规划设计需要的降雨点面关系函数曲线,该研究思路及方法也可为其他城市降雨点面关系研究提供借鉴和参考。
Based on the minute rainfall data of seven rainfall stations within deep tunnel service scope, the areal reduction factor was deduced using the Thiessen polygon method and was analyzed combined with the relevant research results at home and abroad. The function curve of the relationship between point rainfall and areal rainfall which meets the need of the deep tunnel planning and design in the center of Guangzhou City was obtained. The research approach can provide reference for other cities to study the relationship between po
