摘要
针对冻结土体内部三场相互变化规律研究尚不全面的情况,以淮南潘三矿新西风井井筒冻结工程为背景,使用安徽理工大学自行研制的WDC-100型100k N微机控制多功能冻土冻融压缩试验机,采用单因素正交实验法进行了不同冷端温度、大载荷条件下的4组实验。在此条件下得到了黏土的温度场、水分场、位移变形等的变化规律。
As the present research on the three - field mutual variation of freezing soil is not enough. Taking the Pansan new west wind shaft in Huainan as engineering background, 4 sets of experiments were carried out at different cold junction temperature, high load conditions using single factor orthogonal experiment with WDC -100 type microcomputer control muhifunction freezing soil compression test machine developed by Anhui University of Science and Technology. Change law of the temperature field, moisture field, and displacement deformation was obtained.
