Abstract: In seasonally frozen ground regions,low-temperature condition would cause frost heave damage to the concrete configuration of the culvert and change the water temperature,which would result in water freezing and block.Therefore,it is necessary to determine the critical buried depth of the culvert in seasonally frozen ground regions.In this study,a numerical model for culverts in seasonally frozen ground is established by using transient heat transfer equation and Galerkin method.According to the engineering...
