摘　　要：在进行二滩水电站木材过坝联运机出口段及木材入河运行状态试验研究中，根据地形条件和整个传送工艺的要求，在皮带运输段至钢滑道之间设置了弯道滚筒机，确定了弯道滚筒机的曲率半径、宽度、间距和直径等主要参数，并选择最小曲率半径为４５ｍ的弯道滚筒机，按照重力相似准则和１∶１０的比例进行了模型试验。经模型试验证明：所选参数合适，能确保原木由皮带机均匀、顺利地通过弯道滚筒机，满足试验要求的木材过坝量，为工程设计提供了可靠的依据。During the study of running state wood's entering river and exit section of combine convey for timber over dam in Ertan hydraulic power station, the curve drum machine was settled between the exit of conveyer belt and steel chute facility for timber entering river according to terrain condition and the demand of entire transmittal technology. Main parameters of curve drum machine like curvature radius, width, space between drums and diameter were determined. The model test of least curvature radius was taken with the rule of gravitation similitude and the ratio of 1∶10. It is proved by model test that selected parameters are suitable and timber can waltz through curve drum machine. The test demand is satisfied. It provides a basis for the project design.
