| Abstract: | Li, J.; He, X., and Zhou, B., 2019. Simulation for frost heaving damage of concrete lining channels by using XFEM. In: Guido-Aldana, P.A. and Mulahasan, S. (eds.), Advances in Water Resources and Exploration. Journal of Coastal Research, Special Issue No. 93, pp. 264–273. Coconut Creek (Florida), ISSN 0749-0208. Concrete lining plays an important role in channel protection. The existence of seasonal frozen soil has caused different degrees of damage to concrete lining channels. When the concrete lining plate cannot bear the channel base soil frost heaving force or cannot adapt to the channel base soil frost heave deformation, frost heaving damage, such as crack and even rupture, will be produced. In this study, the numerical simulation model of frost heaving damage of concrete lining channels is established. The temperature field is accurately simulated through an equivalent equation of heat conduction. The extended finite element method combined with the thermal coupling method is used in this study to analyze the frost heaving damage of the lining channel. The crack is predicted to propagate under the action of frost heave so that the destruction of the concrete lining channel. The development of the crack and the failure mode of the channel are simulated. It is found that the damage location and degree of lining slabs at different locations of the same section are different. And the crack form is I + II compound crack. The mechanism of frost heave damage of concrete lining canal was revealed, which provides a reference for prevention and control of frost heave of lining canal. [ABSTRACT FROM AUTHOR] |
