摘要
根据高速公路软基处理特点,本文针对具体工程实例,从CFG桩复合地基的设计理论、施工控制和现场试验等几方面,系统的介绍了CFG桩复合地基在高速公路软基滑塌加固中的应用,提出了桩长、桩径、桩间距、桩体强度,以及垫层厚度和垫层材料的确定方法,给出了施工质量控制方法,并通过现场试验进行了可靠性论证,为这种软基处理方法的推广应用提供借鉴依据。
Based on the characteristics of disposal of soft foundation of expressway, this paper aimed at special engineering items, from theory of composite foundation design, construction control, site experimentation and so forth systematically introduced the application of CFG pile in disposal of soft foundation of expressway sliding road-section, provided with the determination method of pile length, pile diameter, pile spacing, pile strength, cushion thickness and cushion material ,gave method of construction quality control and provided with useful warranty to the application of this soft foundation disposal method form reasoning reliability of site experimentation..
