摘　　要：本文通过弹性理论分析，给出了预应力锚杆施加于围岩（开挖边界附近的岩体）的附加应力场和附加位移场，并由此得到预应力锚杆提供给围岩的附加应力状态的普遍形式。在此基础上。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.
