Paper title：Numerical simulation of frost heaving deformation of fractured rocks considering heat-force coupling Paper abstract：Rock engineering in cold regions is susceptible to frost damage phenomenon by the influence of freeze-thaw, in which the frost deformation of fractured rock is the main cause. There is a lack of methods for modeling frost heaving deformation in fractured rocks. Considering the effect of temperature change and water flow, a model of the frost heave deformation of ice in fractures and a numerical simulation method of the frost heave deformation of fractured rocks are proposed. In order to validate the new model as well as the numerical method, three typical factors affecting the freezing deformation of rocks, which are fracture size, number of fractures and fracture inclination, are considered. The frost heaving deformation of rocks under different fracture conditions is measured by the design and production of a testing device for frost heaving deformation of fractured rocks. A three-dimensional numerical simulation model of frost heaving in fractured rock is established, and the correctness of the method is verified based on experimental results. The effects of fracture size, fracture number and fracture dip angle on the rock are analyzed and the validity of the method is verified in two aspects, which are the overall longitudinal deformation of the rock and the frost heaving pressure. Further, the feasibility of applying the method to the fracture extension is tested. The numerical simulation method proposed in this paper can take into account not only the temperature variation but also the size and shape of the fracture. This study can be helpful for the design and disaster prevention of rock engineering in cold regions. Paper type：SCI Tutor 邱文亮
