深季节冻土区涵洞温度场分布规律测试分析
The Test and Analysis of Temperature Field Distribution of Culvert in Deep Seasonal Frozen Region
摘要
Abstract
With reference to the Huo-Bo Railway engineering in deep seasonal frozen region, the law of the temperature distribution outside and inside the culvert are analyzed through site test of temperature field of culvert. The test results show that: (1) the outside temperature field distribution curve changes with the season in a form similar to a sine; ( 2 ) the temperatures of the subgrade body on top of the culvert rises gradually with the increase of the depths subject to low temperature in winter, but are all minus with little difference outside and inside; ( 3 ) the temperature field of the side wall of the culvert presents obvious shady and sunny slope effect, the temperature of sunny slope is about 1. 9℃ higher than that of the shade slope;(4) the temperature differences of test points in the culvert are small and the test points with higher temperature in each culvert section tend to appear in the corner of the culvert, where the temperature is 1. 2 ℃ higher than that at other test points due to the wind flow field. Test and analysis results may provide references for culvert design and construction in deep seasonal frozen region.关键词
