摘　　要：根据相似理论及巷道围岩所处的地质条件,建立深埋高应力软岩巷道的相似材料模型,对深埋高应力软岩巷道的变形规律及破坏特点进行了相似材料模拟试验研究,并测量顶底板变形量和两帮相对变形量以及深部围岩的变形量。得出了深埋高应力条件下巷道围岩的变形规律,并在试验的基础上对围岩的变形原因进行了探讨。The similar material model for deep high-stress soft rock roadway was set up according to similarity theory and the geologic condition of surrounding rock of roadway,the experimental study of similar material simulation was made on the deformation regularity and the destruction characteristic of deep high-stress soft rock roadway,and the deformation of roof and floor,the relative deformation of two sides and deformation of deep surrounding rock were measured.The Deformation regularity of deep roadway under high stress was obtained,and the deformation reason of surrounding rock was discussed based on experiments.
