摘要 膨胀土是一种特殊土,随含水量变化具有遇水膨胀、强度骤减、失水收缩、坚硬而又常有收缩裂隙的高塑性粘土,其胀缩特性主要受其矿物组成成分的控制。膨胀土常给人类的工程活动带来危害,全世界每年因膨胀土造成的经济损失大约为50亿美元以上。本文对双鸭山热电厂地基岩(土)矿物成分、化学成分、胀缩特性等进行了试验研究,结果表明:膨胀土的胀缩特性是以失水收缩为主,并确定了胀缩等级,最后提出了工程建议。 The expansive soil is one kind of special nature soil, it's a high plastic clay of adamancy but usually contracts the crevasse,has the characteristic of expand, strength quickly induced, losing water to shrinkage along with the water content change. Its expansion characteristic is mainly controlled by mineral composition. The expansive soil often bring harm to the humanity's project activity, every year the economic losing is probably above 5 billion dollars because of the expansive soil in the world. This article has carried on the test and research for the foundation rock (soil)' s mineral composition, chemical composition, characteristic of expansion and shrinking to the Shuangyashan thermal electricity company. The result indicated: The expansive soil' s characteristic of expansion and shrinking is mainly on losing water to shrinkage, and confirmed the grade of expansion and shrinking. Finally , it has given the suggestion to the project.
