变冷端温度的人工冻土冻结试验研究

Cold end temperature-changing experimental research on the artificially frozen soil

针对人工冻土边界温度变化迅速的特点展开了变冷端温度的人工冻结试验研究,结果表明采用的试验方法可以较好地控制人工冻土冷端边界温度和土样的初始温度场,这为冻土试验的可重复性提供了保证。

The paper carried out the freezing experimental research on the artificially frozen soil, which is characteristic of boundary temperature changing rapidly. The research result shows that soil freezing tests can present good reproducibility through controlling one freezing soil sample＇s cold end temperature and its initial temperature field as same as the other one using the author＇s method.
