摘要

研究了膨胀土的强度指标c，?与含水量?、干密度及饱和度sr的关系，以及强度与膨胀压力p之间的关系，结果表明：c，tan?和，sr，?的关系与膨胀压力p和，sr，?的关系相似；任何状态的膨胀土的强度，皆可表示为饱和状态的强度和吸力引起的，并可用不同状态土的膨胀压力表示的附加强度两部份。

Abstract

The relationships between strength indexes c

? and dry density ，degree of saturation sr，water content ?

strength and swelling pressure p of expansive soil are researched. The results show that the relationship between c，tan? and

? are similar to that of between swelling pressure p and

?；the strength of expansive soil under any state can be represented both by strength under saturated state and addition strength produced by suction; and the latter can be represented by swelling pressure of soil in various states.
