本文根据对地基土变形特性的分析,采用了考虑地基土粘弹塑性的力学模型,提出相应的地基变形与有效压缩层深度的计算方法。本文方法考虑了地基土变形模量随深度递增及地基荷载与沉降之间的非线性关系,不仅反映了结构性粘土地基变形分布特征,也符合非结构性砂砾类地其变形随深度迅速衰减的规律.本文还结合实际建筑物与承压板的地基土层变形观测,对现有各种有效压缩层深度计算方法进行了比较.比较结果表明,在各种情况下,本文提出的方法比较符合实际.
In this paper, based on the analysis of deformation characteristics of foundation soil, a mechanical model considering the viscoelastic-plastic behavior of foundation soil is adopted, and corresponding calculation methods for ground deformation and effective compression layer depth are proposed. This method considers the nonlinear relationship between the deformation modulus of foundation soil and the increasing depth and the ground load and settlement. It not only reflects the deformation distribution characteristics of the structural clay foundation, but also conforms to the rapid attenuation of the deformation of the non-structural gravel with depth. Laws. This paper also compares the deformation measurements of foundations and soils of actual buildings and pressure-bearing plates, and compares the existing calculation methods of various effective depths of compression layers. The comparison results show that under various conditions, the proposed method is more consistent. actual.
