摘要
In this paper, the dispersion-type tensile cable cited as the secondary reinforced measure. The structure and superiority of this pre-stressed cable are firstly addressed. Considering the stratum softening, calculated formula modified from Shear-Lag Model is presented to analyze the shear strength of grout/matrix interface along the anchored section. Load transfer of the dispersion-type tensile cable of the secondary reinforcement in a highway slope is then analyzed and discussed. The case analysis and monitoring results show that the dispersion-type tensile cable for slope second reinforcement has application prospects.
