摘要: 近年来,由于大量水工构筑物遭到法向冻胀力的破坏而引起人们对法向冻胀力的重视,很多设计、科研、施工人员想了解国内外有关法向冻胀力的计算方法及其准确程度,以便在使用中参考。为此,本文简要介绍了一些计算方法及其主要论点,并对它们进行了分析讨论,对其中有些公式还用我们的实测资料进行了核算,希望它能对法向冻胀力的研究有所帮助,并且能为设计人员提供一些可供选择的计算方法。

Abstract: This article briefly introduced the calculation methods of normal frost heaving suggested by M. F. Kicelev, V. O. Orlov, U. G. Kulicov, N. A. Belitrusin, Seiiti Kinosita, Motonori Enokido E. Penner, Tong Chang-jiang,Gao Mingzhu and Hang Huaguang, Chen Xiaobai et el.These methods were tested by the measured data of the auther of this article. It is found that the study of the relationship between the normal frost heaving force and the foundation area has great practical significance.The actional mechanism suggested by Chen Xiaobai et el. and that the experimental result on the proportion of frost heaving force to the foundation diameters is constant worked out by Seiiti Kinosita are of referential value. The calculation of normal frost heaving force through the frost heaving amount of foundation soil is a simple method. The ways used by Seiiti Kinosita and E. Penner et el. are worth studying. The determination of the frost heaving force in the field through large scale experiments of original soil in laboratory is a method with good prospects.
