英文摘要	Rheological property is one of the main properties of rock. It is close related with engineering's stability, especially for the deep soft rock caverns or tunnels. Instability and damage do not often occur after excavation immediately but come out after long term rheological deformation. It brings many exceptional problems to the engineering designation and construction technology. In addition, water has great influence on the mechanical characteristics of rock. The mechanical characteristics have significant differences between unsaturated and saturated mudstone. In this paper, we take focus on the long term mechanical characteristics of unsaturated and saturated mudstone located in mining area in Huainan. Based on a series of experiments and theoretical analysis, a suitable rheological mechanical model is established and the model parameters are obtained, after then we have a comparative analysis to the unsaturated and saturated model. Compared with the large in situ triaxial creep tests, the laboratory test shows a great agreement with the in situ test. The rheological characteristic of deep soft rock is well reflected. The research work will be provided to realize the rheological mechanics characteristic of deep mudstone, and it has important reference value to the long term tunnel stability analysis of soft rock.
