| Abstract: | The calculation of vibration in the foundation
soil has been carried out by using FEM after adopting barriers(blank rut and fill rut)in
the workshop.A practical method of computer simulation has been presented intead of
physical simulation.The dynamic stress,displacement and vibration frequency distribution
in space and variation in time-domain are acquired by a contrast analysis of the vibration
variation in the foundation soil both before and after adopting different barriers.And a
guide conclusion that can be used to engineering design with practical significance has
been obtained. |
