摘要
通过数值模拟方法分别研究三、四排管直线冻土帷幕平均温度与冻土帷幕厚度、管排间距、冻结管排列形式以及冻结管排数之间的关系。并且通过分析多排管直线冻土帷幕温度场特征,运用温度场拼接和等效方法提出了一种多排管直线冻土帷幕平均温度的计算方法。通过公式计算结果与数值模拟结果的比较发现,该计算方法具有较好的适用性和较高的准确性。
Through numerical simulation method this paper studies the relationship of the average temperature of the three/four-row-pipe straight frozen soil wall with the thickness of frozen soil wall, the distance between pipes and rows, the arrangement form of freezing pipes and the row number of freezing pipes respectively. By way of analyzing the temperature field characteristics of multi-row-pipe straight frozen soil wall, this paper proposes a new calculation method of the average temperature by mathematical splicing method and equivalent method. The comparison between the results of calculation method and numerical simulation method proves that the calculation method has a better applicability and a higher accuracy.
