极端温度变化条件下加筋土挡墙内部温度场数值分析
Numerical analysis of inner temperature field of reinforced-soil retaining wall under extreme temperature fluctuation
摘要
Abstract
To investigate the changing regularity of the temperature field of a geogrid-reinforced soil(GRS)retaining wall under extreme temperature fluctuation,this study focused on a GRS retaining wall in a Urumqi engineering practice.Finite element models were constructed and employed to analyze the inner temperature dis-tribution characteristics of the GRS retaining wall,taking into account the influence of solar radiation.The find-ings indicate a strong correlation between the inner temperature field of the GRS retaining wall and variations in environmental temperature,with the isotherm closely resembling a hyperbolic shape.Specifically,the field within approximately 3.0～4.0 m behind the facing panels and about 2.0 m below the top surface of the GRS retaining wall can be classified as a temperature-sensitive region.Furthermore,the width of this temperature-sensitive region expands in proportion to the thermophysical parameters.The utilization of filling materials pos-sessing enhanced thermophysical properties can effectively alleviate the average temperature gradient;however,the magnitude of the average temperature gradient predominantly depends on the rate of fluctuation in the exter-nal temperature.The maximum depths of frost show an increase with the saturation of filling materials,with the most significant increment observed during the transition from a saturation level of 0 to 0.2.关键词
