| Abstract: | A simulative analysis was carried out upon the foundation stability under load action of newly built buildings above an old goaf by using the FLAC2D finite difference program. The results showed that the method was feasible. It provided a new analytical method for evaluating the foundation stability of newly built buildings above the old goaf. |
