以空间多个测点的观测资料为依据，引入测点坐标而建立的时空分布模型可动态监测任一组荷载时的坝体位移场，当固定坐标时该模型就演变为测点的监测模型。应用上述场理论，用线弹性、粘弹性有限元数值计算方法建立三峡临时船闸３ 号坝段梁挠曲线的时空分布模型 Based on the observation data of multiple measuring points in space, the space-time distribution model established by introducing the measuring point coordinates can dynamically monitor the displacement field of the dam during any set of loads. When fixed coordinates, the model evolves as the monitoring model of measuring points . Applying the above field theory, the spatiotemporal distribution model of the deflection curve of No.3 dam of the Three Gorges Project with linear elasticity and viscoelastic finite element method is established
