摘　　要：利用分数导数Kelvin固体模型,并结合Mittag Leffler函数,在不考虑体积变形的情况下,分析了粘弹性岩体中水平圆形硐室的变形特性,得到了位移及其应变随时间变化的规律;该模型考虑了瞬时弹性变形及其蠕变的非线性特性。With didn't consider the volume deformation, Used the fractional derivative Kelvin model and Combined Mittag-Leffler function, analysis the characters of deformation of viscoelastic horizontal round adits in rocks. Get the regularity of strain and displacement with time; This model considered the instant elastic deformation and nonlinear creeping.
