摘要
为分析万安水利枢纽工程运行对赣江中游水文情势的影响,建立了赣江中游水动力数学模型,研究了万安水利枢纽工程运行前后对赣江中游水文情势变化影响,得到了水位、流量等水文参数的变化趋势和规律。结果表明,万安水利枢纽工程运行前后水位、流量和流速总的变化趋势是一致的,但在局部时段,万安水利枢纽工程运行前后各个位置水位、流量和流速变化范围较大;由于万安水库的调蓄作用,万安水利枢纽工程运行后水位和流量的最大值都有所降低,水位最大值降低范围为0. 137~0. 250 m,最大流量值降低范围为309~405 m^3/s。
In order to analyze the influence of Wan’an Hydraulic Project on hydrological regime in midstream of Ganjiang River,a mathematical model of hydrodynamics in the midstream of Ganjiang River was established. The influence of Wan’an Hydraulic Project on the hydrological regime in the midstream of Ganjiang River was studied before and after the operation of this project. The water level and discharge were obtained from the model,which presents the trend and change law of hydrological regime. The results show that the change trend of water level,discharge and flow velocity are consistent before and after the operation of Wan’an Hydraulic Project,but during some period the change range of water level,discharge and flow velocity are big before and after the operation of Wan’an Hydraulic Project;that due to the regulation and storage function of Wan’an Hydraulic Project,the maximum water level and discharge has been reduced after the operation of Wan’an Hydraulic Project. The reduce range of maximun water level is 0. 137 ~ 0. 250 m,the reduce range of maximun discharge is 309 ~ 405 m^3/s.
