| 摘 要： | 针对三维有初始间隙的接触问题,采用新的接触算法——有限元混合法研究了观音岩水电站混凝土坝和坝后式厂房在上下游水荷载作用下的相互作用。根据坝体和厂房之间不同分缝宽度和分缝高度的计算结果,得出了分缝大小对坝体、厂房变形和应力的影响,为结构分缝设置和安全性评价提供了依据。

| Abstract: | A new model for three-dimensional non-linear contact problem is presented here for the interaction between the gravity dam and the powerhouse of Guanyinyan hydropower station.In this approach,different contact conditions between the dam and the powerhouse are considered,i.e.length and width of the gap.The results including stresses and displacements obtained are compared to the solutions by finite element method without considering contact. This method is shown to be effective and some opinions are given. |
