摘要
本文介绍用自行研制的冰点仪，对４个不同含水率的砂土，在０─１０ＭＰａ条件下，试验研究其结冰温度。研究表明，不饱和水的砂土，其结冰温度与外载无关；对饱和和过饱和水的砂土获得了其结冰温度随外载变化的规律。
This paper demonstrates the experimen ts which are the s tudy on the freezing tempera-ture of wet sand with 4 different water contents under external load of 0─1 0 MPa with aself－deveoloped freezing point meter．The study shows a law that the freezing temperature ofsaturated and super saturated sand varies with external load．As for the unsaturated sand,itis proved by the experiments that the external load can not influenee the freezing point.
