Abstract
Taking the multi-span continuous monolithic floor structure used in a sluice project as an object,Plaxis finite element numerical collaborative analysis is used to investigate the influence of uniform and uneven pile foundation layout on the internal force and settlement value of the floor.By comparing the internal force and settlement values under different pile foundation layout schemes,it is found that the pile foundation layout has a significant effect on the bending moment and settlement of the bottom plate.Among them,the uneven arrangement of pile foundation(especially the arrangement of pile foundation edge and side)is more effective in controlling the bending moment of the bottom plate and reducing the uneven settlement.The numerical simulation results show that the maximum bending moment of the upper floor of pile foundation is significantly reduced and the load of pile foundation is more uniform.The research results will provide theoretical guidance for the design and construction of multi-span continuous sluice floor structure,which is helpful to improve the economy and safety of the project,and also provide a new perspective and method for the optimization of pile foundation layout in similar projects.关键词
