摘　　要：本文用材料力学法计算变形荷载分量、温度分量,并建立变形监控模型。根据现行混凝土重力坝设计规范中对大坝强度和稳定控制条件,拟定变形监控指标。它与坝体变形和应力、稳定计算方法一致,对混凝土重力坝安全监控具有广泛的通用性。With the method of material mechanics,this paper calculated the deformation of load component and temperature component and established deformation monitoring model.On the basis of control condition of strength and stability set by gravity dam design code,defor-mation monitoring index can be worked out ,which is in accordance with the calculations of dam deformation,stress and stability.This method is proved to be universal on security monitoring of gravity dams .
