摘　　要：本文采用有限差分法计算正曲率作用下采动地基上深梁的应力，编制了程序DBST，得出了采动地基梁内的应力分布规律，并在实际工程中得到了应用。A finite difference method is used to analyze the stress experi-enced by deep beams on mining affected foundation.The law governing the distrbution of stress in such beams under the effect of mining has been brought to light with the use of the special program DBST. The method used has found field application.
