摘要
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 .
By using the three dimension visco elastic finite element and fullcourse emulation method, and coupling nonlinear contact problem, the transverse joint aperture of concrete arch dam has been studied in this paper. The changes of aperture in fullcourse have been obtained. The results show that the apertures at the upper and the lower portions of the dam don't satisfy the requirements of the joint grouting of concrete dam. Hence, some engineering measures must be taken to ensure the safety of dam.
