摘要
通过比较线弹性断裂力学中的两种计算应力强度因子的方法 :外推法和奇异单元法 ,得到相应的结论 ;并以某砼坝下游部位出现裂缝为例 ,分析在不利荷载作用下裂缝的稳定性 .
In this paper according to comparing extrapolate method with singularity element method which are the methods of calculating the stress density factor in linear elastic fracture mechanism field,Thus gets corresponding conclusion.Then the cracks in the dowmstream part of a concrete dam are taken as examples.Stabilization of cracks are analysed in disadvantage loadcase.
