Deadman anchoring design for cable logging: a new approach

Cable yarding is still a common system for transporting wood in steep terrain. In the Pacific Northwest and other regions of high productivity forestry, reduced rotation ages for harvest have resulted in a lack of large stumps to serve as anchors for cable yarding systems. One of the most common anchoring alternatives to stumps is buried deadman anchors. Conventional design of these systems has been limited to simplified charts that account for soil resistance, as well as both shear and bending resistance of the deadman, typically a buried log. However, these charts are limited to larger deadman anchors of only Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), which are likely not readily available in modern operations. Thus, revised simplified design charts are proposed considering a variety of different soil failure mechanisms, as well as several different wood types and bending conditions. An updated approach providing a quantitative perspective towards safe anchoring in modern forest operations.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
