摘　　要：水泥土是水泥与原土经人工拌合形成的特殊材料,水泥土强度与水泥强度等级、原土的物理力学性质、搅拌次数及均匀性等多种因素有关,通过对工程项目室内水泥土和现场水泥土桩90 d龄期强度增长特点的研究,总结出水泥土和水泥土桩与龄期相关的强度及竖向承载力特征值计算公式,应用于水泥土桩工程检测及验收,效果良好。The cement mixed soil is a unique material formed by artificially mixing cement and soil. The strength of the cement mixed soil is related to many factors such as cement mixed soil strength grade, physical and mechanical properties of original soil, and mixing times and uniformity. By studying the strength increment features of 90 days curing time of the indoor prepared cement mixed soil samples and the on-site soil-cement columns, this article proposes a formula to predict the age-related strength and characteristic value of vertical bearing capacity of cement mixed soil and soil-cement column the acceptance test methods of the age-related soil-cement columns.

关 键 词：配比试验 水泥土强度 静载试验 竖向承载力特征值
