| 摘 要： | 在冻土工程领域,国内外已经展开了广泛的基础性研究,取得了丰硕的成果.对冻土路基温度场问题,目前已有理论依据和计算方法,但大多只考虑了第一类边界条件.本文利用有限元软件,同时考虑了辐射、蒸发、换热等各种边界条件,对冻土路基非稳态温度场进行了计算分析,根据计算与实测结果的对比分析,从而有力地验证了本文采用有限元计算方法的可靠性,并且进一步根据计算与实测结果,对冻土路基非稳态温度场进行了计算分析.

| Abstract: | In the filed of frozen soil engineering projects,there are many basic research at home and abroad and have get plentiful results.Now,there are theoretical foundation and computing methods,but,which only take the first boundary condition into account.In this paper the writer takes advantage of the finite element software and at the same time takes the boundaries into account such as radiation,evaporization,heat transfer and so on to calculate and analyze the transient temperature field of the frozen subgrade... |
