摘要
选取军塘—西二110 k V输电线路工程红砂岩层G24杆塔桩基础为研究对象,基于弹塑性理论,并采用有限差分方法,数值模拟了杆塔桩基础在上拔荷载作用下地基岩土体变形破坏过程,获得杆塔桩基础地基土体在上拔荷载作用下的变形破坏模式,为红砂岩地区输电线路杆塔基础设计提供参考。
The paper selects red sand stone G24 tower pile foundation of Juntang-Xi5 er 110 kV transmission line as an example, follows elastic theory, applies finite difference method, numerically simulates foundation geotechnical rock deformation damage process of tower pile foundation under pulling load, and obtains tower pile foundation soil deformation damage mode under up-lifting load, which has provided some guidance for designing transmission line tower pile foundation in red sand stone area.
