苏州市城市中心区建设工程设防水位计算研究

摘要:

基于苏州市城市中心区内枫桥水文站1977～2016年和苏州水文站1952～2009年历年实测最高水位资料以及枫桥站1983～2017年实测年最大1h、6h、24h雨量资料,通过采用P-Ⅲ频率适线法和排涝计算进行苏州市城市中心区100年一遇洪水位以及遇100年一遇24h暴雨时内涝水位计算,结果表明：城市中心区大包围西北片区、东南片区建设工程100年一遇防洪水位分别为4.86m和4.38m,防涝水位分别为4.70m和4.38m,设防水位分别取4.70m和4.38m。

Abstract:

SBased on the measured maximum water level data of Fengqiao hydrological station from 1977 to 2016 and suzhou hydrological station from 1952 to 2009 in the urban center of Suzhou, and the measured maximum rainfall data of Fengqiao station from 1983 to 2017 at 1h, 6h and 24h. the water level of 100-year flood and the waterlogging water level of 100-year and 24-hour rainstorm in central district of Suzhou city are calculated by using P-Ⅲ frequency fitting line method and waterlogging calculation. Results show that the flood control water level of 100-year in the northwest and southeast areas of the urban central area is 4.86 meter and 4.38 meter respectively, The waterlogging water level is 4.70 meter and 4.38 meter respectively, and the fortification water level is 4.70 meter and 4.38 meter respectively.
