Calculation and Analysis of Bearing Capacity of Double-Layer Foundation Based on Prandtl Assumption

Full Text(PDF, 495KB)

Author: Yaping Wang

Abstract: Based on the basic concept of Plandell's assumption, the plasticity balance principle is applied to analyze the bearing capacity of the two-layer foundation, and the formula of bearing capacity of the two-layer foundation is obtained. The variation of bearing capacity of the foundation under different soil conditions is analyzed, and different calculation parameters are obtained. The effect on the ultimate bearing capacity of the two-layer foundation. The study found that: (1) For homogeneous soils, the formula obtained in this paper is the same as the Plandell formula; (2) the cohesive force of the soil, the soil bulk density above the foundation, and the aspect ratio have less influence on the bearing capacity of the foundation than the internal friction angle. Much; (3) The upper and lower layers of different strength ratios have different critical depths and increase with the increase of the relative strength of the upper layers. (4) This paper assumes that the foundation is completely smooth and ignores the influence of the bulk density of the foundation soil, which is not consistent with sand.

Keywords: Double Layered Foundation, Bearing Capacity of Foundation, Prandtl, Internal Friction Angle
