林业架空索道上、下力点的定位,是继选线工作之后的重要工作.它在很大程度上决定线路的走向、安装工程量和生产效能.一般情况下,山上粗大立木的根部(或伐根)是索道的天然上力点.而山下公路旁由于不具备像山上的天然条件,常用人工地锚作下力点.多年来,我们在实践中多次参考了日本学者虾名常义有关人工埋入式地锚强度 The positioning of the downward force point on the forestry overhead cableway is an important task after the alignment work, which largely determines the direction of the line, the installation volume and the production efficiency.Generally, Root) is the ropeway’s natural force point.While the mountain road because it does not have the natural conditions like the mountains, the commonly used artificial anchors as the force point.For many years, we have repeatedly referred to the practice of Japanese scholars shrimp name Changyi artificial buried Into the anchor strength
