Abstract (2. Language):
In Japan, soft and sandy soils and steep slopes were native problems and usually caused difficulties in forest road
construction. In addition, there were many crushing zones in mountainous forested area, and underground water
often sprung out from stones and rocks in these crushing zones. This underground water often caused road
degradation and should be drained. Some forest road retaining technologies had been introduced recently for
stabling spur roads. One is L-shaped steel retaining wall technology called L-shaped mesh wall. It is easy to
construct and underground water can be drained easily. The other is reinforced soil wall using thinned logs and
geotextile called TK wall. In this study, the bearing capacity and usage of these technologies were analyzed
based on the points of terrain, bearing capacity, and future possibility. L-shaped mesh wall was effective when
applied to cross the short section of crushing zone. TK wall was easy to construct on steep slopes with narrow
clearing width for roadway by its perpendicular filling slope, and provided environmental friendly landscape
with recovered vegetation from the seed contained at surface as well as using thinned woods. Both technologies
made easier to construct spur roads on slopes with soft soils but it was clarified that they needed appropriate
drainage systems and their regular maintenance for economical use.
