摘要
根据软岩的单轴压缩蠕变试验，讨论了软岩强度和弹性模量的时间效应问题。软岩的强度和弹模均为时间的函数，它们的变化规律具有相似性，都随时间的延长而降低。最后，分析了岩石损伤的时间效应，提出了长期弹模和长期损伤变量的概念。
Based on the creep test of uniaxial compression for weak rock, the time dependent behaviours of strength and elasticity modulus of weak rock are discussed in this paper. Both strength and elasticity modulus of weak rock are the functions of time, and their changing law with time is similar-they are descreased with time. At last, time dependent behaviour of rock damage is analyzed, and the long term strength and the long term damage are put forward.
