Abstract:

The bed rock in the lower part of the slope where the tower base of 35 kV high-voltage line at the right of Jinping Hydropower Station is located is bare and the covering layer is loose. The cracks exist in the slope body and the slope slides under the storm, which threatens the safety of the tower base, and must be treated. Therefore, the measures of shotcrete and rock bolt support, systematic anchor rods, mesh sprayed concrete, lattice beam, anchor pile, anchor cable reinforcement etc. were adopted. A detailed introduction to the construction method is given. The stability of the tower base was improved after the treatment.

Key words: tower base, base treatment, high side-slope, Jinping Hydropower Station
