摘要
依托湘江土谷塘航电枢纽车江坝址设计方案,建立了坝址河段二维正交曲线水流数学模型。首先采用天然资料对模型进行率定,通过有关参数调整,使数值计算成果与天然实测资料达到精度要求。然后将航电枢纽工程仿真植入率定好的模型。利用航电枢纽模型,模拟了湘江土谷塘航电枢纽车江坝址河段典型泄流方式的水流情况,分析了河道流速分布特征,给出了引航道口门区和引航道内部纵向流速和横流等与通航有关的参数。结合JTJ 305—2001《船闸总体设计规范》要求,对枢纽通航水流条件进行了评定。展示了航电枢纽数值仿真模拟技术投资少、时间短、成果丰富、方案易优化的特点。
Based on a study for the layout of navigation-power junction at Chejiang dam site of Tugutang on Xiangjiang River,we established the orthogonal curve two-dimensional current mathematical model.Firstly the model was verified with the nature current materials,and some parameters were adjusted so that the calculated result by the model was consistent with the real-measured data.Then the emulating navigation-power junction was embedded into this model.By the navigation-power junction simulation model,the typical discharge ways of the junction was simulated,the current distribution characteristics was analyzed,and some parameters relating to navigation including the longitudinal and cross flow in the entrance area of the approach channel and in the approach channel.Finally,the navigation current conditions were evaluated according to the Code for Master Design of Shiplocks（JTJ 305—2001）.I revealed the features of less investment and time,abundant fruit and easy scheme optimization of this simulation technique..
