樹木を伐採せずに、かつ景観に配慮したロックボルト、ユニットネット併用による自然斜面の安定工法に関する基礎的な研究を行った。The stabilization technique of natural slope which maintained landscape and trees have been proposed. However, this method’s guidelines of design have not been established, because the mechanism of reinforcement is not clarified. In this paper, the laboratory and the in-situ test were carried out in order to obtain basic data of the “Unit Net” used by this method. As the results, it is clear that not fixing “Unit Net” at the intersection distributes the stress more widely than fixing “Unit Net”. Besides, it is recognized that the distribution of the stress is depended on the location and number of the rock bolt.
