摘要：
During geologic investigation for Tongjiezi damsite on Dadu river in China, a typical kind of epigenetic time-dt:pendent structures was discovered, which was different from both general geologic structures and superficial structures. The study indicates that it originated from time-dependent deformation and releasing of residual strain energy in rockmasses at shallow depth in the course of overburden unloading caused by regional erosion. A geomechanical model test was conducted to study and verify the formation mechanism and evolution process of this structure. The model test and its results are described in detail in this paper.
