摘要
将轨道梁的温度作用看作是随机函数。从统计的角度出发,按照50年及100年重现期,利用环境因素的统计特征通过数值积分模型计算了轨道梁的温度作用值极值。计算采用了一维的热传导理论,并且利用实测数据验证了数值模型的准确性。
Temperature effect of track beam is seen as the random function. From the perspective of statistics, we use the statistical characteristics of environmental factors and numerical integration model to calculate Extreme Value of Track Beam on Temperature Effect on the basis of 50 and 100 years return period. We utilize the onedimensional heat transfer theory in the above Calculation, and the accuracy of the numerical model is validated by the measured data.
