【 摘 要 】

Skidding trail sites are reinforced with slash to keep them from rutting by numerous skidding vehicles passes. As the number of passes is not uniform on the site, it is possible to reduce slash usage as the material for reinforcement. The amount of slash should be enough to keep safety characteristics of the slash covering for the definite number of passes. The investigation results of the skidding vehicle passes influence on rutting along the skidding trail (the length of skidding trail 150 m) are presented. Model of vehicle is a crawler skidding vehicle TDT-55A with a cable-winch. Six sites with various numbers of passes were studied. There were sites with 10; 12; 22; 24; 34; 36 passes. The amount of slash to be laid on the sites was determined: slash density should be - 18 kg/m2 for 10 passes of the site; 22 kg/m2 for 12 passes; 35 kg/m2 for 22 passes; 37 kg/m2 for 24 passes; 45 kg/m2 for 34 passes; 46 kg/m2 for 36 passes. For all sites with slash reinforcement the depth of the rut was not more than 220 mm after any number of passes compared with the sites without slash reinforcement with rut depth of 300 mm after just 6 passes. To reinforce a skidding trail, 27 % of the total slash amount are enough compared with 90 % commonly used in the similar conditions.
