摘　　要：为了提高水泥土筒桩在工程领域的应用水平,本文以开发原理结合工程实践经验阐述了其设计、施工及检验验收的控制要点。结果表明水泥土筒桩相较于传统的高压旋喷桩有节约材料、受力合理的优点,在地基处理方面有巨大的应用潜力,如大范围推广使用将取得良好的经济和社会效益。In order to improve the application level of cement-soil tubular pile in the engineering field,this paper expounds the control points of its design,construction,inspection and acceptance based on the development principle and engineering practice experience. The results show that compared with the traditional high-pressure jet grouting pile,cement-soil cylinder pile has the advantages of saving materials and reasonable stress,and has great application potential in the field of foundation treatment. If this foundation treatment was widely used,we will get the good economic and social benefits.
