目前,通常采用土力学中计算不冻土容重及干容重的方法来计算冻土容重和干容重。这种计算方法,必须测定冻土体积、冻土重量及烘干后的重量。由于试验工作量大,冻土体积不易测准,计算结果往往有误差。本文提出根据冻土含水量、冻土中不冻水含量和土的比重来计算冻土容重和干容重。这种方法,只需测定冻土重量及烘干后的重量,而计算结果又较准确。这就为在地基土冻结期间及春融期间
At present, the method of calculating the bulk density and dry bulk density of the frozen soil in soil mechanics is commonly used to calculate the frozen soil bulk density and dry bulk density. This calculation method must determine the volume of frozen soil, the weight of frozen soil, and the weight after drying. Due to the large amount of test work, the volume of frozen soil is not easy to measure, and the calculation results often have errors. This paper proposes to calculate the frozen soil bulk density and dry bulk density according to the moisture content of frozen soil, the frozen water content in frozen soil and the specific gravity of soil. In this method, only the weight of frozen soil and the weight after drying are determined, and the calculation result is more accurate. This is during the freezing of the foundation soil and during the spring
