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。 Saline soil is widely distributed in the western part of Jilin Province. In recent years, due to the frost heave of saline soil, the building (structure) is damaged more and more frequently. Taking the saline soil in Nong’an area of ​​Jilin Province as the research object, the frost heaving test of saline soil was carried out by using the programmed high and low temperature test machine indoors. The results show that the frost heaving amount is not only related to temperature, but also to the compaction degree and water content , Soluble salt content and other factors. The experimental results in this paper are helpful to take effective measures to control the damage caused by frost heave of saline soil.
