| 摘 要： | 通过对实测和计算结果的分析,揭示出冻土路堤中存在显著的横向热差异问题,指出了路基中的横向热差异是由各边界因素的横向差异引起的,路基阴坡面和阳坡面吸收热量的差异使阴坡面下冻土层厚度大于阳坡面。还分析了横向热差异对路基稳定性的影响。

| Abstract: | After analyzing the test and calculated data,it is pointed that obvious transverse thermal difference occurs in the frozen-soil embankment,and the transverse thermal difference is resulted from the transverse difference of the external factors and the surface material properties.Then the heat absorbing difference between the sunny slope and the shady slope of the embankment is proved into,it is indicated that the thickness of frozen soil under shady slope is greater than sunny slope. The paper suggests that transverse difference of external factors should be fully taken into consideration in engineering design. |
