Abstract

The invention discloses a group pile displacement determination method and apparatus. The method comprises the steps of determining initial displacements of foundation piles in group piles and a displacement transfer coefficient matrix of the group piles; according to the initial displacements of the foundation piles and a displacement transfer coefficient, determining internal forces and displacements generated by mutual influence of the foundation piles in the group files; and according to mutual influence parameters, determining the internal forces and the displacements of the foundation piles in the group files. The technical problem of relatively low calculation precision of group pile displacement due to no consideration of mutual influence between the foundation piles in the group piles and the foundation piles is solved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method and a device for determining displacement of pile groups. Background technique [0002] Cap pile group foundation is a relatively common form of foundation, widely used in high-rise buildings, railway bridges, energy and other industries. How to accurately calculate the displacement and internal force of pile groups under vertical and horizontal loads is the focus of pile group analysis, which is of great significance to the design and construction of pile group foundations. [0003] Pile group loading is divided into vertical loading and horizontal loading. At present, there are two main methods for calculating the internal force of vertical displacement of pile group: [0004] 1) Numerical calculation method [0005] Numerical calculation methods include boundary element method, finite element method or difference method. The numerical calculation method takes into ...
