Multi-physical Field Coupling Simulation of Hygro-thermal Deformation of Concrete
Hygro-thermo-mechanical model is presented for investigating hygro-thermal defromation of concrete based on the coupling effect of multi-physical field and transfer mechanism of moisture and heat in porous medium.Then the COMSOL software is used to solve the hygro-thermo-mechanicial coupling question in an interactive environment.The feasibility of the model and method were validated by HUNDT experiment and were compered with the result of hybrid analytic-FEM method.The hygro-thermal deformation of a lake tunnel were also numerical simulated by COMSOL and the numerical results and fiber Bragg grating (FBG) monitoring data were comperative analyzed.The results of COMSOL simulating result is more colse to the field test data than that of analytic-FEM method.
