摘要 利用焓式有限元方法对各路基的温度特性进行了三维数值分析,并通过对比分析得出:透壁通风管的降温效果最好,非透壁通风管的降温效率次之,普通路基的降温效率最差。 Using the enthalpy-based finite element method,the three-dimensional temperature characteristics of roadbeds have been numerically analyzed. The results indicate that the refrigeration efficiency of the ventilation roadbed containing apertured rentiduct is the most favorable among three types of roadbeds.
