本文讨论以气候条件为影响因素的地土冻结深度公式。首先讨论这种公式形式的选择方法,并根据我国若干地区冬季土中0℃达到深度的观测资料,推导出一个考虑地热影响的地土冻结深度计算公式,利用在有雪复盖条件下的观测资料,提出推导地土冻结深度公式的方法。最后,对苏联拉普金地土冻结深度公式作了分析和讨论,证明拉氏公式乃是本文公式的某一地区特例,具有明显的地区性,从而指出在幅员广阔的国家里,采用单一的拉普金公式作为确定地土冻结深度的方法是不合理的。
This paper discusses the depth of ground freezing formula based on climatic conditions. Firstly, the selection method of this formula form is discussed. According to the observation data of 0°C reaching depth in winter soil in some regions of China, a formula for calculating the depth of soil freezing considering the effect of geothermal heat is derived and used for observation under snow cover conditions. Data, proposed a method for deducing the depth of ground freezing formula. In the end, the depth formula of the depth of frozen soil in the Soviet Union is analyzed and discussed. It is proved that the Laplace formula is a special case of a certain region of the formula of this paper, with obvious regionality. It is pointed out that in a vast country, a single pull is used. The Purkinje formula is unreasonable as a method for determining the depth of ground freezing.
