Abstract

Abstract

Unified strength theory is introduced to consider the influence of intermediate principal stress, the calculation formula of allowable soil resistance on anchorage section of anti-slide piles is deduced. Mean while, the semi-analytical and semi-numerical weighted residual method is used to calculate the required soil resistance on anchorage section of anti-slide piles, and a new rational method to determine anti-slide anchorage length is put forwarded. The proposed method is applied to two calculation examples, the distribution of req uired soil resistance on piles and distribu tion of allowable soil resistance with different unified strength parameter s are obtained, the rational anchorage length is determined by comparative analysis of the distribution diagrams. The analysis result also shows that the allowable soil resistance on piles which is gained by unified strength theory increases with unified strength parameterb.
