摘　　要：某超高层办公楼项目,其下基础地质复杂,桩入岩深度不一,且部分桩下存在碎裂岩,采用三维有限元分析程序Midas/GTS进行分析,结合工程实际,考虑上部结构刚度,根据超前钻、详勘报告建立土体模型,分析在复杂地质条件下桩基础受力性能与底板应力分布,供类似工程参考借鉴。The foundation of a certain high-rise office building project has complex geological conditions with varying depths of pile penetration into rock,some piles are founded on fractured rock.In this paper,three-dimensional finite element analysis software Midas/GTS was employed to analyze the foundation.Considering the stiffness of the superstructure and based on advanced drilling and detailed investigation reports,a soil model was established to analyze the stress performance of pile foundations and the stress distribution in the base slab under complex geological conditions,providing a reference for similar projects.
