摘　　要：文章结合平阳县鳌江滨水文旅长廊项目——平阳县鳌江标准堤加固工程施工实践,依据高压旋喷桩的成桩机理,探索试验水、空气、水泥浆的压力、流量、提升速度、旋转速度及水泥浆的掺量、比重等各项技术指标与成桩质量间的关系,根据高压旋喷桩施工工艺特点,在施工过程中严格把控各工序的施工质量,严格控制由试桩获得的各项技术参数,及时管控可能出现的施工偏差,认真落实注意事项,利用质量控制的基本原理方法,做好事前、事中、事后各项工作,阐述、总结淤泥质地基处理中采用大直径高压旋喷桩的施工质量控制方法。Based on the construction practice of Pingyang Aojiang Standard Embankment Reinforcement Project of Pingyang Aojiang Binhai Hydrological Tourism Corridor Project,and the piling mechanism of high-pressure jet grouting pile,this paper explores the relationship between the technical indexes of water,air,cement slurry pressure,flow rate,lifting speed,rotation speed,cement slurry content,specific gravity and pile forming quality.According to the construction technology characteristics of high-pressure jet grouting pile,the construction quality of each process is strictly controlled in the construction process.The technical parameters obtained from the test pile is strictly controlled,and the possible construction deviation is timely controlled while conscientiously implementing the matters for attention.The basic principles and methods of quality control is used to do a good job before,during and after the work,elaborate and summarize the construction quality control method of using large diameter high-pressure jet grouting pile in the treatment of silt foundation.
