摘要
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
Based on the observed data, introducing the surveying point coordinates,the temporal and spatial distribution model of displacement field can be used to monitor the displacement field of dams for any load group, and when the coordinates are fixed,the model is changed into a monitoring model of surveying points.Based on the above mentioned field theory by use of linear elastic and viscoelastic FEM,the temporal and spatial displacement field distribution model for the temporary lock dam block 3 of the Three Gorges Project is establised in this paper.
