| 摘 要： | 通过动态剪切蠕变试验，分析了不同剪切荷载比的层间相对滑移曲线形态．发现以最大抗剪强度的0．2～0．3倍作为剪切蠕变荷载能够获得稳定发展阶段；建立了以动态剪切蠕变稳定度为指标的层间稳定性的评价方法。结果表明：应用动态剪切蠕变试验和动态剪切蠕变稳定度对层间稳定性能进行评价是可行的。

| Abstract: | The forms of relative slip curves of interlayer under different shearing force ratios were analyzed by dynamic shearing creep test.It was found out that a stable development phase could be obtained when taking a force of 0.2-0.3 times of the maximum shearing strength as the shearing creep force.A method of interlayer stability evaluation was established,taking the dynamic shearing creep stability as an index.The results indicate that the evaluation of interlayer stability by dynamic shearing creep test and ... |
