Abstract

In the each loading stage, strain and creep strain occurs instantaneously on the axial and lateral of fractured. Instantaneous strain leads to the 80% overall specimen deformation. The axial strain is about 2–3 times larger than the lateral strain. Instantaneous strain completed time and deformations under each loading stage decrease when the loading time increases. With the increasing of loading, axial strain and lateral strain of fractured phyllite present the approximate linear curve growth change. With increasing of axial stress, the relationship between the lateral strain and axial strain transform from the linear increased trend to the index increased trend. With the increasing of moisture content, the axial deformation and lateral deformation of fractured phyllite increase. The curves of axial strain and lateral strain under soaked for 10 and 15 days condition are similar. The modified Burgers model can describe each creep stage of fractured phyllite which have high fitting precision, less fluctuation and high reliability. Therefore, modified Burgers model can provide an effective way to analyze the creep characteristics of fractured phyllite.
