Axisymmetric Loaded Rigid Circular Plate on Multi-layered Soil

AI Zhi-yong MEI A-min (Department of Geotechnical Engineering,Key Laboratory of Geotechnical and Underground Engineering of Ministry of Education,Tongji University,Shanghai 200092,China)  
Based on the equivalent settlements of rigid circular plate,the continuity and smooth contact conditions between subsoil surface and rigid circular plate,the dual integral equation of the interaction stresses between the rigid circular plate and multi-layered soil,was deduced after introducing Hankel transform.By resolving the dual integral equation,the solution of the rigid circular plate on multi-layered soil was obtained by using transfer matrix solutions for displacements and stresses of multi-layered soil and Hankel inverse transform.Numerical calculation and analysis were also carried out by computer program. The calculational result shows that for homogeneous soil,it is adequate to consider the displacements and stresses within the area of 4 times of the diameter of rigid plate,and it is unfit to extend the solution for the homogeneous soil into the multi-layered soil and the non-homogeneous soil,as the lamination and non- homogeneity have a considerable affects on the displacements and stresses of the soils.
