摘要
在流变断裂学基础上引入可靠性理论，提出在考虑荷载及混凝土性能随机性的条件下，解决了流变影响的混凝土裂纹体可靠性的分析方法。通过实例计算，反映了流变可靠性指标βＲＬ明显的时间相依性，得出了流变极限可靠指标βＲ的概念，对建筑结构设计规范和水工结构规范的修订有一定的参考价值。
A kind of analytical means to solve the reliability of the crack body for concrete is put forward in this paper, on the base of rheological fracture, which was considering the random of load and the properties of concrete. The examples show that the time-dependent response of rheological reliable index R exists. So the concept of the rheological limit reliability index RL is formed, which is referential to the revision of the design standards of building and irrigation-work-structures.
