摘　　要：采用MTS815电液伺服试验系统对某煤矿底板泥岩进行了三轴压缩蠕变试验,得到轴向应变、环向应变、体积应变与时间的关系曲线;建立了基于Burgers模型的泥岩非线性蠕变方程;理论曲线与某煤矿底板泥岩蠕变试验曲线基本吻合,表明建立的Burgers模型能够模拟泥岩底板蠕变力学特性。The Creep test on mine floor mudstone is carried out under triaxial compression by MTSS15 electro-hydraulic servo-controlled rock mechanics testing system. The test curve of axial strain, circumferential strain, volumetric strain and time are obtained.According to the test results, the nonlinear creep equation is established, theoretical curve and mudstone creep test curves are consistent. The results show that Burgers model can simulate mine floor mudstone creep properties.
