考虑加筋效应的抗拔群桩变形解析解
Analytical solutions of deformation of anti-pull group piles considering reinforcement effect
摘要
Abstract
The theoretical calculation of the deformation of uplift group piles currently falls behind its engineering practice because of the approximation of theoretical assumption and the lack of consideration of the pile -pile rein-forcement effect .To solve this key problem , displacement decomposition of a single pile in uplift group piles foun-dation was conducted .On the basis of the shear deformation mode of thin-walled concentric cylinder and elastic su-perposition principle , a method for calculating the deformation of uplift group pile foundation , taking into account the reinforcement effect of piles , was proposed .Calculation results of finite element and model test results were compared with the calculation results of the proposed method .Results show that the theoretical analysis method could calculate the deformation of uplift group piles foundation well .The calculation of the interaction of group piles in the paper conforms to the actual engineering practice of group pile system .Therefore, the proposed theoretical method has a high theoretical and practical engineering value , and a promising application prospect in the deforma-tion analysis and design practice of large-scale uplift group piles .关键词
