摘　　要：基于滑动测微计,成功监测了某拱坝蓄水期及运行期坝基岩体变形规律,探测了裂隙、断层、软弱夹层分布和变形量。监测结果表明,坝基岩体在蓄水后处于受压的工作状态,岩体累积位移量比较小,坝基表面岩体变形最大,随着深度的增加,岩体变形越小,总体上反映出基岩的变形规律。The paper monitors successfully deformation law of arch dam foundation in storage period and operation period and detects intercalation distribution and deformation quantity of crack,fault and weak with sliding micrometer.The results show rock of dam foundation is in compression situation after storage,cumulative displacement is small,deformation of surface rock for dam foundation is large and rock deformation decreases with depth increasing which reflect deformation law of foundation rock.
