三峡临时船闸3#坝段位移场确定性模型

Deterministic Displacement Field Model for the Temporary Lock of Dam Section No.3 of the Three Gorges Project

通过引入空间三维坐标，阐述了确定性空间位移场的建模机理及方法，即水压分量、温度分量及时效分量均采用有限元计算结果．应用粘弹性有限元模拟大坝的加荷过程，通过计算粘性位移，经拟合得时效分量．结合三峡工程临时船闸３ ＃ 坝段，建立其位移确定性模型．

Through the application of field theory,the principles and methods of establishing the deterministic displacement field model are discussed,and the components of water pressure,temperature load and time effect are calculated on the basis of the results from FEM.The loads on the dam in the storage period are simulated by the visco elastic finite element method,the time independent component can be fit by the calculated visco displacement.These theories and methods are adopted in the building of the deterministic displacement field model for the temporary Lock of the Three Gorges project.
