摘要
本文从分析气侯因素着手,论述了任意坡向、坡度的坡面太阳辐射量计算方法和地下水埋深对冻土深度的影响,找出了基土冻结、冻胀与年均气温、气温年变幅,太阳辐射量和地下水埋深的关系,建立了任意坡向坡度的基土冻结深度和冻胀量的预报数学模型。利用该模型进行计算,可以大大节省工作量。
Based on the analysis of climatic factor, the paper has discussed a calculation method of solar radiation dosage on the arbitrary slope and slope direction and effects of ground water leved to depth of frozen earth; found the relationship between the ground water level and congelation and frost expanding of base soil with the mean annual temperature, annual ranges of temperature and solar radiation; set up a methematical models predicting the depth of frozen base soil and volume of frost expanding. A great amount of calculation work can be saved if the calculation is done based on the method provided by the paper.
