摘要
针对水平定向钻进技术施工过程中土体变形的影响及规律研究不足,缺乏相关参考理论的问题,本文借助ABAQUS有限元软件,结合工程实例,对不同孔径、不同铺设深度钻孔周围土体变形进行数值模拟,研究水平定向钻孔施工后孔洞附近的土体变形规律,为施工组织设计及后续设计研究工作提供科学可靠的指导。
ABAQUS finite element software is adopted in the paper in view of the influence of soil deformation and lack of regular research, deficient related reference theory in horizontal directional drilling technology construction process, engineering example is combined for numerical simulation on soil deformation around the holes with different apertures and different laying depths, the soil deformation laws near the hole after horizontal directional drilling construction are studied, thereby providing scientific and reliable guidance for construction organization design and subsequent design study work.
