依托湘江土谷塘航电枢纽工程，采用资料分析、整体定床水流模型与船模航行试验相结合的研究方法，对船闸分别位于狭窄连续弯道中的下游反向弯道凸岸和凹岸2种枢纽布置方案进行了研究，并结合其它将坝线布置在弯道段的已建或拟建的枢纽布置情况，对狭窄连续弯道河段枢纽平面布置应遵循的一些原则进行了探讨，提出对于上游为急弯、下游为反向弯道的狭窄连续弯道河段，当枢纽坝线位于下游弯道段时，宜采取将船闸布置于凸岸侧的分散布置方式。

Based on the Tugutang navigation-power junction project on Xiangjiang river, we analyzed and compared two layout schemes in terms of flow discharge capacity, shiplock and ship navigation conditions, etc. by means of data analysis, integral fixed bed flow model, and ship model navigation test. In the two schemes, the shiplock is located respectively on the convex bank and the concave bank of the reverse bend in the downstream of continuous narrow meandering river. Moreover, according to the layout of other junctions built or planned to be built with the dam axis on river bend, we discussed the principles in designing the layout of hydro-junctions on continuous narrow meandering river. Data analysis, integral fixed bed flow model and ship model navigation test were employed in the research. It's proposed that as for junctions used for navigation and power generation, the layout of dam axis and shiplock axis should be the focus. For hydro-junctions on continuous narrow meandering river with abrupt bend in the upstream and reverse bend in the downstream, the layout should abide by the following principles: 1. the navigation route should be on the same bank with the shiplock. 2. when the dam axis is in the downstream bend, the shiplock should be on the convex bank.
