| 摘 要： | 陈村重力拱坝在施工和运行过程中，坝体下游面出现了一条较大裂缝。在分析以往跨缝插筋和改性环氧灌浆处理效应的基础上，提出了预应力锚索加固处理方案，并对锚固力大小，作用位置，加固后的应力状态等进行探讨，得到了较合适的锚固力及应避免的不利水位，其方法可供深入研究大坝加固效应的参考。

| Abstract: | n the course of contstruction and operation. a large crack was found on the downstream face of Chencun gravity arch dam. On the basis of the study of the effects of embedding steel bars(1973)and cpoxy resin grouting(1987). the reinforcing scheme of prestressed anchoring is put foward.and the position of action of the anchoring force and the stress state is studied.The anchoring force suitable for the practical case of Chencun gravity arch dam and the disadvantageous oporation water level which must be avolded are obtained. The result of the present study provides a basis for reinforing practi ce in the furture. |
