采用全过程仿真粘弹性空间有限单元法、耦合非线性接触问题 ,对混凝土拱坝横缝开度进行了计算研究 ,得出了横缝开度随时间变化的情况 .计算说明靠近地基和坝体上部的横缝开度较小 ,不满足接缝灌浆要求 ,应采取必要的工程措施以确保大坝安全 .
Through the whole process simulation of viscoelastic finite element method and coupled non-linear contact problem, the horizontal joint opening of concrete arch dam is calculated and studied, and the opening of transverse joint changes with time is obtained.The calculation shows that close to the foundation and the dam The upper transverse joint opening is small, does not meet the requirements of joint grouting, engineering measures should be taken to ensure the safety of the dam.
