| Abstract: | In this paper,on the basis of ground movement and deformation obtained from simulation tests of dynamic mining process,additional internal forces of a reinforced concrete frame structural building on the ground surface over goaves are calculated with finite element method;distribution features of additional internal forces and the relationship between ground movement and deformation are analysed;the effect of additional internal forces on the safety of buildings is also discussed. |
