An Urgent Slope Reinforcement for a Power Transmission Tower Foundation

摘要

The main focus is to present an urgent reinforcement for a power transmission tower foundation beside a slope. The method is based on the theory of the uplift and down-pressure lines in low slope. The strategy adopts the geosynthetic-reinforced gunite concrete and two-storey retaining wall to reinforce the slope. The results show that the theory of the uplift and down-pressure lines in low slope can be used in the slope with the height of 10m by combining retaining wall reinforcement. The heavy excavation under the transmission tower foundation is avoided by using the inclined back along the edge of the balance-weight retaining wall. The compound clay backfill provides sufficient strength for two-storey retaining walls beside the slope.
