摘    要:对岩石蠕变的应力-应变比分析方法进行了探索。蠕变是岩石重要的力学性质之一。岩石在各个应力水平下的蠕变曲线具有几何相似性。根据岩石蠕变的应力-应变比曲线可以近一步分析得到等时模量曲线。在岩石蠕变本构描述十分复杂、至今没有成熟的理论的情况下,应力-应变比分析方法具有十分重要的现实意义。

关 键 词:蠕变  几何相似  等时模量

Abstract:In this paper,we have discussed the method for analysis of stress-strain ratio associated with rock creep.Creep is one of the most important characteristics of rock.Under different stress states,rock creep curves show the behavior of geometry-comparability.We can gain the isochronous-modulus curves from the curves of stress-strain ratios.The constitutive equation of rock is so complex that well accepted method is still not available in the open literuary erure.At present,the analysis ofstress-strain ratio can be a good approach to further the examination of rock creep behavior.
Keywords:Creep  Geometry-comparability  Isochronous-modulus  Rock mechanics
