摘要
为解决改扩建工程中新旧路基差异沉降的问题,在分析泡沫轻质土的物理特性的基础上,重点通过室内试验研究了气泡含有率、原料土、固化材料、水泥标号、含水量、养护时间等因素对无侧限压缩特性的影响。结果表明:气泡含有率及配合比对泡沫轻质土的物理特性和无侧限压缩特性影响较大;泡沫轻质土的无侧限抗压强度随着气泡含有率的增大而减少;在实际工程应用中应选择合适的材料和工艺参数。研究成果可为解决同类工程问题提供参考。
In order to solve the problem of differential settlement between the new and old subgrade in the reconstruction and extension engineering, on the basis of analyzing the physical characteristics of foam lightweight soil, through the indoor test, this paper mainly studied the influence of the factors, such as bubble rate, raw soil,curing materials, cement grade, water content and maintenance time, etc. on the unconfined compression characteristics.
