摘要
建立渠道基土冻胀模型,推导出基土温度场控制方程和应力应变有限元公式。进而为分析应力场、应变场打下基础。通过ANSYS软件分析出基土温度场特性,得出结论:①渠道底板和边坡板附近土壤受地温影响较大,随着深度的增加温度差逐渐减小。②随着深度的增加,土壤的温度趋近于某一恒定值。土中温度场趋近于稳定状态。
Based on building a channel basic soil frost mode,soil temperature field controlling equations and stress-strain finite element formulation are derived,which lays foundations for analysing the stress field and strain field.By ANSYS software to analyze characteristics of soil temperature field,the results are that： ①the soil of channel bottom and near the slope plate are affected a lot by temperature,and the temperature difference gradually reduces with the depth increases.②as the depth increases,the soil temperature approaches a constant value.Temperature in the soil tends to the steady state.
