| 摘 要： | 应用线弹性、粘弹性有限元数值计算方法，以空间多个测点的观测资料为依据，引入测点坐标建立三峡泄洪２＃坝段空间位移场的确定性模型。该模型可以动态监测泄洪２＃坝段在任一组荷载下的位移场，以此分析和评价大坝变形性态。

Temporal and Spatial Distribution Model of Displacement Field of Flood Discharge Dam Section 2 of the Three Gorges Project |
| |
| Abstract: | Based on the observed date of the measuring points by use of linear elastic and viscoelastic FEM and through introduction of the coordinates of the measuring points,a deterministic temporal and spatial distribution model of displacement field is built for section 2 of the flood discharge dam of the Three Gorges Project.This model can be used to dynamically monitor the displacement field of the section 2 under any set of loads so as to analyse the dam deformation characteristics. |
