Abstract

Abstract

Contemporary force models of double row piles are mainly established on the basis of soil arch effect, ignoring interactions between top ring beam and link beam. In this paper, a force model of frame anti-sliding piles is presented to solve the problem efficiently for its spatial force analyzing techniques, which takes double row anti-slide piles as a single-layer multi-span frame structure composed of piles, beams and soils. A calculation approach for the model is proposed. It decomposes the frame structure into two parts along sliding surface, and deformation equations are rebuilt up correspondingly under pile lead border condition, continuous deformation of strong point, static force balance and deformation coordination between top ring beams and pile leads. A program is developed using MATLAB. Finally, the approach is applied in the test of Three Gorges reservoir geo-hazard prevention project, and the result shows that it is suitable for force calculation of frame anti-sliding piles.
