摘要
介绍了中国、美国、法国、印度对膨胀土的判别分类标准,中国标准采用自由膨胀率,美国标准采用多种方法,法国标准按膨胀应力分类,印度标准采用多指标综合判别分类膨胀土。同时,介绍了在不同判别分类标准下,膨胀土地区基础工程采用的微型桩、短桩、应力抵消法等施工方式。
The identification and classification criteria of expansive soil in China,America,France and India are introduced.For Chinese,American,French and Indian code,free swelling ratio,multiple methods,swelling pressure and multi-index comprehensive method is adopted respectively.Meanwhile,the construction methods such as micro pile,short pile and stress offset method for foundation engineering in expansive soil area under different identification and classification criteria are presented.
