摘要
在处理饱和软黏土地基时,水泥土搅拌桩加固技术效果较成熟,应用较广泛。本文结合南沙地区采用水泥土搅拌桩加固珠江三角洲滨海冲积平原饱和淤泥软土的工程实例,介绍了水泥土搅拌桩的质量影响因素、施工工艺、参数设计等关键环节,对完善水泥土搅拌桩的参数设计、现场管理、质量控制等具有一定的借鉴作用。
In the treatment of saturated soft clay foundation,the effect of cement mixing pile reinforcement technology is mature and widely used.Combined with the engineering example of cement soil mixing pile in strengthening saturated silt soft soil in Nansha area,the key links of cement mixing pile,such as quality influencing factors,construction technology,parameter design,and quality inspection,are introduced which can be used for reference to improve the parameter design,site management and quality control of cement mixing pile.
