摘　　要：建立山秀水利枢纽整体物理模型,对山秀船闸扩能工程口门区布置方案进行试验。上游口门区所处弯曲河道下游左岸,基础条件较差,方案布置及优化受限制条件较多,水流条件难以满足通航要求,结合工程实际情况从宏观角度出发,从上游弯段起沿程布置潜坝群以调整工程河段的主流位置,将口门区对岸扩挖以补充河道过流断面并为河势提供调整空间,使得口门区及航道过渡段的水流条件满足通航要求,并减少对河道泄洪影响。The overall physical model of Shanxiu Water Control Project was established,and the layout scheme of the entrance area of Shanxiu Ship Lock Expansion Project was tested.The upstream estuary was located on the left bank of the downstream bend river,where the foundation condition was poor,the layout and optimization of the scheme were limited,and the flow conditions were difficult to meet the navigation requirements.Based on the actual engineering situation,from a macroscopic point of view,submerged dams were arranged along the upstream bend to adjust the mainstream position of the engineering reach,and the opposite bank of the estuary area was expanded to supplement the cross section of the river and provide the river regime.Adjust the space so that the flow conditions in the entrance area and the transitional section of the channel can meet the navigation requirements and reduce the impact on the flood discharge of the river.
