| 摘 要： | 采用三维有限元方法对小湾高拱坝多种工况下的坝体应力变形进行了仿真计算,计算中考虑了封拱灌浆过程及水库分期蓄水过程对坝体应力的影响。计算结果表明,施工过程对坝体运行期应力有显著影响,给出了仿真计算荷载步数目,为类似工程的拱坝应力分析提供了参考依据。

| Abstract: | 3-D FEM is adoptedto imitatively analyse stress and deformation of Xiaowan high arch dam under multiple operating conditions. The effect of crown filling and water impoundment processis considered in calculation,and the results are compared with the results of analysis without consideration of crown filling and water impoundment process.This comparision show that construction process has remarkable effecton stress state of damduringoperation period,and the results are more real and reasonable.Study on stress state of high arch dam during operation period must consider crown filling and water impoundment process.Amount of simulated construction steps to get a quite real and reasonable result is proposed for Xiaowan high arch dam,providing reference for analysis of stress state of arch dams in similar project. |
