摘　　要：针对赤山闸(下)水位能否代表句容河水位进行分析探讨。首先选取赤山闸(上)、赤山闸(下)和前垾村3个代表站,对其历史特征水位进行了对比分析,结果表明无论是汛期各月多年平均水位还是历史最高水位,赤山闸上下游水位差明显,达0.76~0.96 m,而赤山闸(下)与前垾村站水位差基本一致,介于0.01~0.04 m。其次选取2015~2018年4场典型洪水,对其洪水过程进行了对比分析,结果表明在赤山闸开闸期间,赤山闸(下)与赤山闸(上)水位接近,赤山闸(下)与前垾村水位差明显,最大达1.97 m,赤山闸关闸期间,赤山闸(下)与前垾村站水位基本一致,水位差为-0.02~0.05 m。通过分析,建议句容河警戒水位设置采用前垾村站代表站更加合理。Whether the under-gate water level of the Chishan Gate could represent the Jurong River water level was analyzed and discussed.Firstly,three representative stations of Chishan Gate(up-gate)station,Chishan Gate(down-gate)station and Qianhan Village station were selected,and the characteristics of its historical level was compared and analyzed.The results showed that both the average water level in flood season months and the highest level for many years,the level difference of upstream and downstream water level of Chishan Gate was obvious,which was up to 0.76~0.96 m,while the the level difference of Chishan Gate(down-gate)station and Qianhan Village station was basically the same,ranging from 0.01 to 0.04 m.Secondly,four typical floods from 2015 to 2018 were selected and the flood process was compared and analyzed.The results showed that during the opening of the Chishan Gate,the water level of the Chishan Gate(down-gate)and the Chishan Gate(up-gate)was close.The water level difference between the Chishan Gate(down-gate)and Qianhan Village was obvious,and the maximum was 1.97 m.During the closing of Chishan Gate,the water level of the Chishan Gate(down-gate)and Qianhan Village Station was basically the same,and the water level difference was-0.02~0.05 m.Therefore,it's suggested that using the Qianhan Village Station representative station as the Jurong River warning water level setting was more reasonable.
