摘要
本文用三点弯曲试件，进行了不同应力强度因子水平的徐变断裂试验，得到了应力强度因子水平与断裂时间的关系．研究了混凝土龄期对断裂时间的影响．同时，对裂缝扩展作了分析．
The experiment of creep fracture for concrete by using a serious of three points bending specimens. The relationships between stress intensity factor levels and time of creep fracture have been obtained. The effect of concrete curing period on time of creep fracture has been discussed. Furthermore, the crack propagation has been analized.
