中文摘要：
为了选取合适的黏弹性本构来描述节理岩体,首先通过评述文献指出岩体的品质因子（Q值）在一定频率范围内均不随频率变化;接着详细推导了三参数标准线性固体和朱-王-唐（ZWT）模型的Q值与频率的关系,发现ZWT模型在一定频率范围内能得到稳定的Q值,较适宜于描述岩体特性;最后探讨了ZWT模型参数的计算方法,指出利用ZWT模型各个构件的物理意义来计算模型参数是一种比较合理的方法.
英文摘要：
This paper points out the quality factor Q of rock mass is independent of wave frequency in certain frequency range through reference reviewing. Then, the relationships between Q value and the frequency for the three-parameter standard linear solid model and the Zhu-Wang-Tang （ZWT） Model are derived in detail. ZWT Model, which can get a constant Q in certain frequency scope, is more suitable to simulate the property of rock mass. Finally, the calculation method for the ZWT Model parameters is explored. Results show that it＇s a reasonable way to evaluate the model parameters by using the physical meaning of each element.
