| Abstract: | In this paper, a theoretical analysis of elastic mechanics is used and the applied stress field and displacement field on prestressed anchor in wall rock are given. A general form of the formula for analyzing stress fielf in wall rock is shown. On this basis；the mechanical mechanism of prestressed anchor is expounded. |
