为深入探究木寨岭隧道工程中炭质板岩的流变力学特性,在不同条件下,对现场取得的岩样进行单轴和三轴压缩蠕变试验,并对炭质板岩的蠕变特性进行分析,描述了炭质板岩的流变特性,得出了瞬时应变占总应变的比例为80%～90%,以及高围压下的流变多为等速流变等结论;采用Burgers流变本构模型,对试验数据进行参数拟合分析,得出了3组不同围压下炭质板岩流变本构方程的弹性模量、黏性模量、黏滞系数等主要参数。

Uniaxial compressing creep tests and triaxial compressing creep tests are made on the rock samples taken from the site of Muzhailing tunnel,and the creep properties of the carbonaceous slate are analyzed and described,so as to study the rheologic and mechanic properties of the carbonaceous slate.Conclusion is drawn that the instantaneous strain takes 80% to 90% of the total and that most part of the rheology under high confining pressure is uniform rheology.The major parameters of the carbonaceous slate,such as the elastic modulus,viscous modulus and viscidity coefficient,are obtained by means of fitting analysis on the test data using Burgers rheologic constitutive model.
