摘要
在总结历史治理经验的基础上,通过模型试验研究了神背嘴滩的碍航特征及成滩原因。通过新开右槽、建整治建筑物等措施调整汊道分流比和束水攻沙,使航道尺度增大到2.7m×50m×560m,改善了枯水弯、浅、险的碍航问题,保证了航槽的稳定。整治方案可为山区河流急弯滩险治理提供借鉴。
Based on the historical regulation experience,the obstructing features and formation causes of Shenbeizui Shoal were studied by the model experiments.Using regulation measures such as dredging the right channel and building the regulating structures,the diversion ratio of flow was adjusted,and the flow was concentrated for scouring sediment,then the channel dimensions were enlarged to 2.7 m ×50 m ×560 m after regulation.The obstructing problems were solved,and the navigation channel was stable.The regulation schemes can provide reference for the waterway regulation on branching rapids of mountain rivers.
