移动荷载作用下饱和土体上筏板-上部结构的动力响应分析
Dynamic responses of the vibration of the raft-superstructure on the saturated soil under moving load
摘要
Abstract
Based on Blot' s theory and the minimum potential energy principle as well as the thin plate theory, the superstructure, raft and soft are assumed to be a whole system according to the substructure method. The system must satisfy the continuity conditions at the interfaces between the superstructure, raft and soil surface. Considering the compatibility condition that the vertical displacement of the interface between the raft and the saturated soil should be equal, the integral equation ac- counting for the vertical coupling of the superstructure-raft system with the saturated soil subjected to a moving load is con- structed. Using the numerical inverse transform technique,the forces and displacements of the superstructure,plate and saturated soil at any time are obtained. Some numerical results are presented to demonstrate the capacity of the proposed model. Also,the influence of load velocity on the superstructure is investigated in this paper.关键词
