Abstract: According to the calculation result of stress condition for Baiyunjiang reservoir arch dam with Abqus software (a large finite element calculating software), the conclusion was got as follows: the peripheral joint invalidated after anchorage and grouting, then the stress concentration around it increased significantly. In the condition of high water level, the tensile stress of upstream damface around peripheral joint exceeded the allowable tensile stress.

摘要： 通过采用Abqus 大型有限元计算软件对该水库拱坝应力状态进行的计算, 结果表明: 周边缝在锚固与灌浆后失效, 失效后周边缝附近应力集中现象显著增强, 且在高水位条件下, 周边缝附近上游坝面拉应力均超过允许拉应力。
