복합체역학에 기초한 Soil nailing의 해석기법에 관한 연구

초록

Soil nailing technique which has been widely used as a slope reinforcement method is mostly analyzed by the limit equilibrium method and the design procedure is usually performed by the commercial S/W. In this case, the nails are modelled by the cable or the beam element and the numerical difficulties are encountered in some cases. In this study, a new nail element via homogenization technique is proposed and the related equations are derived so that the new element can be implemented into the commercial S/W such as FLAC. The results are compared with those by the conventional analysis method and the advantages/disadvantages of the proposed model are investigated. Future work and the extension of the proposed model are finally discussed.
