| Abstract: | Kinds of theoretical calculation of soft foundation under the negative pressure condition are introduced;and the settements are calculated by using the plane strain FEM.In the computation,the rhcology and damage due to construction disturbance of soft soil is considered.The calculated results are quite argee with the in-situ measured data.The calculated method is reasonable. |
