摘　　要：在北方寒冷地区,由于冬季低温持续时间较长,对于施工工序的编排造成了极大的影响。在某项目施工中,存在施工可用工期短、地质条件差、工程量较大的情况下,基础工程的施工进度成为了项目合理安排工期的重点。在项目冬季基础工程施工过程中,采用了超流体混凝土长螺旋钻孔灌注桩施工技术,通过合理地安排施工工期和超流态混凝土长螺旋钻孔灌注桩施工技术改进应用研究,在保证质量的前提下,大大提高了施工进度,为整个项目按时完工提供了重要的保障条件。In cold northern regions,the prolonged duration of low temperatures in winter has had a significant impact on the arrangement of construction processes.In cases where the available construction period is short,geological conditions are poor,and the amount of work is large,the construction progress of basic engineering has become the focus of reasonable project schedule arrangement.In the winter foundation construction process of a certain project,the construction technology of ultra fluid concrete long spiral drilling and grouting piles was adopted.Through reasonable arrangement of construction period and the application of ultra fluid long spiral drilling and grouting pile construction technology,the construction progress was greatly improved while ensuring quality,providing important guarantee conditions for the timely completion of the entire project.
