中文摘要：

吉林省西部地区广泛分布着盐渍土。近年来由于盐渍土冻胀而造成的建(构)筑物破坏的现象越来越频繁。以吉林省农安地区盐渍土为研究对象,通过在室内采用程序式高低温试验机进行盐渍土的冻胀试验,结果表明,冻胀量不仅与温度有关,而且与压实度、含水率、易溶盐含量等因素有关。本文试验结果,有助于对由盐渍土冻胀造成的破坏采取有效的防治措施。

英文摘要：

Saline soil is widely distributed in Western part of Jilin province .In recent years the phenomenon of damaged construction in buildings (structures) is becoming more and more frequent caused by the soil frost heave .In this paper ,saline soil in Nong’an area Jilin Province has been taken as the research sub‐ject ,and through indoors program type high and low temperature test machine saline soil frost heaving test has been made .The test results indicate that ,frost heaving amount is not only related to the temperature , but also related to many factors such as compaction degree ,moisture content ,soluble salt content ,etc . The results of this test are helpful to take effective measures to prevent and control the damage caused by frost heaving of saline soil ,and have very important theoretical and practical significance .
