摘　　要：通过对含盐水泥土进行大量的室内试验,分析含水量、龄期、水泥用量、含盐量对水泥土强度的影响,结果表明:含盐量对水泥土强度的提高或减小有一个阈值。当盐渍土的含盐量高于或低于这个阈值时,会对水泥土产生不同的作用。关于盐类对水泥土强度的影响从机理上进行阐释,可以总结出高含盐量对水泥土破坏作用的对策。In order to investigate the effects of water content, curing time, cement content and salt content on the strength behavior of the cemented clays, a series of indoor tests are performed on cemented clays. A threshold is acquired, which reflects the influence of salt content on cemented clays strength＇s advance or decline. The influence of salt content on cemented clays is different when the salt content of saline soil is above or below the threshold. In addition, the influence mechanism of salt on the strength of cemented clays is explained, so some countermeasures against the destructive effect of high salt content on cemented clays are summarized.
