Application of Pre-stressed Cable Bolt in the Reinforcement Construction of High Slope of the Expressway

Abstract:

With the advantages of reasonable structure, handy workmanship, wide adaptability, speedy construction and small cost, the technology of pre-stressed cable bolt has been used in various engineering construction. Good result is proved in a running year. The geological condition and stability analysis of the slope as well as the parameter design are introduced; the experience is summarized in the design and the construction procedure, which include drilling, putting cable, grouting, and tension locking.
