立地ㆍ機能別 林道構造의 改善에 關한 硏究 = Studies on the Improvement of forestroad Structures with Site and Fuction

다국어 초록 (Multilingual Abstract)

This study was conducted to analysis of three national forestroad structures that constructed in korea from two to three years ago, compared with the korea and other countries forestroad standard as to obtain necessary information for improve forestroad.
Data of 12 factors related with forestroad structures ad its characteristics were surveyed 530 plot, which set up at intervals of 40m from beginning of forestroad.
The results obtained in this study were as follows;
1.Forestroad located in order to middle mountain(51.8%), Top mountain(24.9%), and Side mountain(23.3%), which seemed that surveyed areas is high slope region.
2.Average forestroad width was 5.2m, which showed 1~2m exceeding over forestroad standard(3.5~5m)
3.Average grandient of forestraod was not exceeding 12%, but by its maximum gradient, a part(5%) of forestroads were exceeding over 15%.
4.Average cut and fill-slope length were 6.2m, 11.2m(over 6m : 64.2%, 67.2%), and average cut and fill-slope grandient were 114.2%, 80.1%.
5.Average side-ditch size was 0.26㎡, which showed that good results, but average side-ditch was 28.7cm, which showed that lower than desired standard.
