摘要: <正>探讨木材在滑道水平曲线段的运动规律以及滑道模断面布置形式。为林区集材滑道的设计和架设选线提供了理论依据。

Abstract: This paper studies the movement of logs on the horizontal curve section of chute.The force analysis of the log on horizontal curve is made.The moving speed of logs on the curve is derived from theoretical analysis and compared with the result from a Russian formula.Finally,the cross profile arrangement is also discussed.
