The study indicates that the frost heaving character of the meal sand is decimus of silt clays. And its frost heaving quotiety is seldom influenced by the different freezing end temperature and water content. Thus the surroundings influence is in the small area when the artificial freezing method is used in sand and no-stickiness soil.

研究结果表明粉砂冻胀率是淤泥质粘土冻胀率的十分之一，冷端温度、含水量两个因素变化对其冻胀率几乎不产生影响，因此在砂性等无粘性土中应用冻结法对周围环境危害较小。
