摘　　要：在工程实践中,与单向水泥搅拌桩相比,双向水泥搅拌桩具备加固深度深、桩身强度高、土体扰动小的特点,能有效保证软基加固的工程质量。文章主要介绍了双向水泥搅拌桩的成桩原理及其优越性,并结合道路工程实例,分析探讨了双向水泥搅拌桩法的设计参数、施工工艺、质量控制要点、质量检测等。In engineering practice,compared with unidirectional cement mixing pile,bidirectional cement mixing pile has the characteristics of deep reinforcement depth,high pile strength and small soil disturbance,which can effectively guarantee the engineering quality of soft foundation reinforcement.This paper mainly introduces the pile forming principle and superiority of the bidirectional cement mixing pile,and analyzes and discusses the design parameters,construction technology,quality control points and quality inspection of bidirectional cement mixing pile method combined with road engineering examples.
