摘要
为探讨典型红砂岩的蠕变特性,并为该类岩石边坡的稳定性预控等工程问题提供参考,选取开尔文-伏尔特(Kelvin-Voigt)蠕变模型,采取分级增量循环加卸载方式模型进行了典型红砂岩的蠕变试验,获取了典型红砂岩的应力-应变关系及其随时间变化的特性,通过选用元件组合的开尔文-伏尔特模型进行数据拟合,得到了红砂岩通用的蠕变本构方程。该结果可为深入研究含典型红砂岩条件的滑坡等地质灾害预防和较好的解决岩体蠕变损失等问题提供参考借鉴。
In order to study the creep properties of typical red sandstone,and provide reference for the engineering problems such as the stability control of the red sandstone slope,the selected Kelvin Voigt creep model is analyzed,and the creep test of typical red sandstone is carried out by the incremental cyclic loading and unloading method,thus the stress of typical red sandstone is obtained.The stress-strain relationship and its characteristic with time vary,and the general creep constitutive equation of red sandstone is obtained by fitting the experimental test data.The results can be used as a reference for the in-depth study of geological hazards such as landslides with typical red sandstone conditions and how to reduce the creep loss of rock mass.
