| 摘 要： | 对链子崖危岩体软弱夹层的室内剪切流变试验进行了综述，作出了蠕变的位移一时间曲线，并对曲线进行了适当的变换处理，求得软弱夹层的长期强度。进而根据蠕变曲线的特征，以Burgers模型和Kelvin－Voigt模型分别描述了当剪应力大于或小于长期强度时的两种蠕变曲线，并简述了上述工作的实际工程意义。

| Abstract: | The paper describes the indoor shear creep experiment for the week intercalated bed in the dan-gerous rock body of Lianzi Cliff, gives the displacement-time curves of creep. The permanent strength of the week intercalated bed is obtained by means of conversions. Then, according to the properties of the creep curve, we make use of Burgers Model and Kelvin-Voigt Model to describe the two kinds of curves of creep,which correspond to shear stresses larger and smaller than permanent strength, respectively. |
