Analysis of Key Influencing Factors on the Quality of Cement Mixing Piles in Deep and Soft Soil Layers with High Water Content

富水深厚软土地层下的水泥搅拌桩处理效果关键在于成桩质量控制。文章依托实体工程项目,通过现场对比试验的方式,结合钻芯取样检测和复合地基检测情况,对比分析了水泥掺量、水灰比和复搅遍数等施工参数对水泥搅拌桩成桩质量的影响,提出了适宜富水软土地层的水泥搅拌桩施工参数,为同类地层的水泥搅拌桩设计、施工提供参考。

The key to the treatment effectiveness of cement mixing piles in deep and highly water-saturated soft soil layers lies in the quality control of pile formation.This paper,based on real engineering projects,employs on-site comparative tests,combined with core sampling inspections and comprehensive ground assessments,to analyze the influence of construction parameters such as cement content,water-cement ratio,and the number of mixing cycles on the quality of cement mixing pile formation.It proposes suitable construction parameters for cement mixing piles in highly water-saturated soft soil layers,providing reference for the design and construction of cement mixing piles in similar geological conditions.
