摘　　要：三峡工程双线五级船闸深层岩体变形监测成果表明,船闸开挖引起的岩体垂直变形表现为回弹,最大回弹变形10.39mm;岩体水平向位移表现为向闸室方向,最大变形为26.14mm,随着开挖的结束,变形基本趋于稳定,目前高边坡深层岩体处于稳定状态。Deep rock mass deformation monitoring of TGP's double-line five-grade ship lock shows that the rock mass vertical deformation, caused by the ship lock excavation, presents rebound, the maximum rebound deformation is 10.39 mm; horizontal displacement moves to the ship lock chamber, the maximum deformation is 26.14 mm. With the end of excavation the deformation approximately trends to be stable, and at present the deep rock mass of high slope is in the steady condition.
