摘要/Abstract

摘要： 对膨胀土胀缩机理进行了阐述，剖析了膨胀力概念，指出GB/T50279-98界定的膨胀力为最大膨胀力或极限膨胀力，提出自然膨胀力概念及其试验方法。首次开展了自然膨胀力随增湿程度变化规律的试验研究，并对膨胀力随增湿程度、干密度大小、起始含水率等因素的变化规律以及等同土样进行不同程度脱湿后的膨胀力变化规律开展了试验研究，得到了诸多有价值的结论，使对膨胀力概念的认识更加深入，其应用也更符合工程实际。

Abstract: The swelling-shrinking mechanism of expansive soils was expounded; and the swelling force concept was analyzed. It was pointed out that the swelling force defined by nomenclature standard GB/T50279-98 is the maximum welling force or limiting swelling force. Then a new concept of physical swelling force was put forward, as its test method. It was the first time that the study was carried out about the variation regulation of physical swelling force changing with moistening degree. And it was performed that the trial research on the rules of swelling force with moistening degree, primary dry density, primary moisture content and so on, as well as the rule of swelling force with identical soil sample after various degree dehumidifying. Accordingly, some valuable conclusions were drawn, which made it more deeply to catch on the inotion of swelling force and more practically to be utilized.

Key words: expansive soil, swelling-shrinking mechanism, swelling force, physical swelling force
