| 摘 要： | 研究了膨胀土的强度指标c,?与含水量ω、干密度γd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γd,sr,ω的关系与膨胀压力p和γd,sr,ω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 , sr, ? are similar to that of between swelling pressure p and , sr, ?；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. |

| Keywords: | expansive soil strength swelling pressure dry density saturation degree water content |
