Soft rock tunnel which is buried deeply in high ground stress is often accompanied by large deformation of geological disaster in construction process, which seriously affects the safety of construction. In order to overcome this engineering problem and to further reveal the mechanism of large deformation in sort rock tunnel, in this paper related literature and books written by the experts and scholars at home and abroad in recent years are referred, the latest research status and progress of the serious deformation are analyzed, the methods and means to control the large deformation in soft rock tunnel are summarized, and the development direction of this question's future studies is pointed out. It is meaningful and valuable to carry out the systematic studies in mechanism of large deformation in soft rock tunnel and mechanical characteristics in the process of construction and explore the new ways and methods that control the large deformation in soft rock tunnel.
