FIELD: transport.SUBSTANCE: proposed method comprises routing thoroughfare from forest store to forest resource base, routing branch roads from main road at optimum angles in their fixation zones with shift from equilibrium position toward forest store, and routing spur roads from said branch roads. Spur roads in branch road fixation zone part located inside developed resource base are routed toward the branch road at the angle equal to optimum angle of branch road adjoining to the main road. Spur roads in the branch road fixation zone located on the forest store side are routed toward branch road at right angle while every branch road is shifted from equilibrium position by magnitude ?, km, equal to ?=1/2sin ?(1+sin?)[kbd/ kkb- d(1-sin?)}; i=1, 2, ?, N, where ?is optimum angle of adjoining of i-th branch road to main road, deg; kis the factor of main road development (elongation); bis specific costs of removal of logs via main road, ruble/(m·km); dis the width of zone of adjoining to i-th branch road, km; kis the factor of development (elongation) of the spur road; kis the factor to allow for fraction of logs removal mean distance via spur road related to spur road length; bis specific cost of logs removal via spur road, ruble/(m·km); N is quantity of branch roads.EFFECT: decreased power intensity of logs removal.1 dwg |
