摘　　要：随着桩基技术的发展与新技术的推广应用,桩基工程对施工的质量、经济性、安全性、高效性等也提出了多方面的要求。旋挖灌注桩因具有工作效率高、环保性强、泥浆排放量少、现场施工文明化水平高等特性,能够适应桩基工程的需求,受到了建设单位及施工单位的一致青睐。而随着施工场景的复杂化,常规的旋挖灌注桩工艺已无法满足工程需求,必须结合工程现状,制订契合工程需求的工艺体系。本研究从施工工艺创新角度出发,提出了解决以上复杂环境的方法,具有一定的推广价值。With the development of pile foundation construction technologies and promotion of new technologies,there are many requirements for the construction quality,economy,safety and efficiency in pile foundation engineering.Rotary excavation for cast-in-place piles features high efficiency,high environmental performance,little slurry discharge and high level of on-site civilized construction,which is adapted to pile foundation engineering and favored by employers and construction units.Considering complex construction scenarios,however,the conventional rotary excavation for cast-in-place piles no longer meets engineering requirements.Instead,a technology must be developed based on the engineering situation and needs.From the perspective of construction technology innovation,a solution to the aforesaid complex conditions was proposed in this study,which has some value of promotion.
