摘要:

针对支护结构对高层建筑地基基础沉降变形分布特征的影响,利用有限元数值模拟手段,建立考虑排桩支护结构影响的复合地基基础的三维模型,以地基基础差异沉降为控制指标,以改变地基变形模量来描述地基支承刚度的空间变化,讨论排桩支护结构存在条件下,复合地基支承刚度空间变化对地基基础沉降等值线分布规律的影响.研究表明,排桩支护结构对地基基础沉降变形分布特征有明显影响,复合地基基础基于差异沉降控制的空间变刚度设计需考虑支护排桩的作用效应.研究成果对减少建筑物基础边缘部分桩、降低基础差异沉降,有效改善筏板和上部结构次应力具有

Abstract:

Aiming at the influence of supporting structure on the settlement deformation distribution characteristics of foundation of high-rise buildings, a three-dimensional model of composite foundation considering the influence of pile support structure is established by finite element numerical simulation method, and the spatial change of foundation support stiffness is described by changing the deformation modulus of foundation by changing the differential settlement of foundation foundation as the control index, and the influence of spatial variation of composite foundation support stiffness on the distribution law of foundation settlement contour under the presence of pile support structure is discussed. The results show that the pile support structure has a significant influence on the settlement deformation distribution characteristics of the foundation, and the spatial variable stiffness design based on differential settlement control of the composite foundation needs to consider the effect of the pile support. The research results have the effect of reducing the piles at the edge of the foundation of the building, reducing the differential settlement of the foundation, and effectively improving the secondary stress of the raft and superstructure
