Thermodynamic properties of water during phase transition in fractured rock are discussed.
The cycled freezing and thawing (phase transition) of water in rock fractures and soil has long been recognized as an important factor in mechanical weathering.
Unfortunately, the freezing pressure is affected by multiple factors, such as temperature, features of fracture, and physico-mechanical properties of rock.
This paper put efforts to illustrate thermodynamic properties of water during phase transition in rock, and then simulated freezing pressure caused by phase transition of water in crack of rock.
Thermodynamic Properties Rock mass is a typical kind of porous media, where the water is mainly stored in the cracks.

Choosing M-C model for filling sand in the sand filling subgrade stability analysis, calculation parameters of sand filling subgrade was from indoor mechanical property of material experiment.
The cohesion c changes from 0KPa to 24KPa, the friction angle changes from 20°to 40°, other factors are the same to being used above, and the safety factor is coming to shown in Fig. 4.
The stability of sand filling subgrade is being affected with the slope ratio, the subgrade height, the presence or absence of the surrounding soil and the thickness of it, the top seal coat, pavement structure etc. if the height is higher than some value, the safety factor will decrease quickly, and the safety factor will also decrease quickly with the increase of slope ratio.
