淄博新暴雨强度公式下LID建设影响探讨

Discussion on the Impact of LID Construction under the New Rainstorm Intensity Formula in Zibo

淄博市现行的暴雨强度公式为20世纪80年代初编制,为了落实《国务院办公厅关于做好城市排水防涝设施建设工作的通知》(国办发[2013]23号)精神,在气候变化和城市化快速发展背景下,区域短历时强降水的强度和分布特征均发生了显著变化。2014年12月,由淄博市气象局、淄博市住建局审核,淄博市气象局编制的新一版主城区暴雨强度公式已开始应用。对比新旧公式和城市发展情况,结合城市低影响开发理念,探讨设计需要注意的问题。

The current formula of rainstorm intensity in Zibo City was compiled in the early 1980s.With the implementation of the spirit of Notice of the General Office of the State Council on the Construction of Urban Drainage and Waterlogging Prevention Facilities(GBF[2013]No.23),significant changes have taken place in the intensity and distribution characteristics of regional short-duration heavy precipitation in the context of climate change and rapid urbanization.In December 2014,the new version of rainstorm intensity formula for the main urban area,which was compiled by Zibo Meteorological Bureau and reviewed by Zibo Meteorological Bureau and Zibo Housing and Development Bureau,began to be applied to practice.By comparing the old and new formulas with the urban development,and combining with the concept of urban low-impact development,the issues that require attention in design are discussed.
