澜沧江三道拐河段航道整治模型试验研究

The Model testing Research of Regulation of Channel for San Daoguai River Reach of Lan Chang Mekon River

论述了三道拐河段河床复杂地形、碍航原因等情况，在认识滩性的基础上进行工程对比试验，提出了治理应以增大弯道半径和改善水流流态为主，从而保证中。

This paper deals with the complicated topography of the river bed of San Daoguai River reach and the main hinderance of navigation.Engineering comparative tests have been done based on the recognition of beach nature.It is suggested that the river regulation mainly be the increase of radius of curved path and the improvement of flowing condition in order to guarantee safe navigation under both moderate water level and low water level.
