摘要： 结合破碎基岩地区380 m超高层项目，基于数值分析方法探讨了计算岩石地基稳定性的强度折减法、荷载增大法以及节理面强度折减法。提出基于多种弹塑性求解器、统一节点不平衡力相对容差的“破坏标准”，以及基于超高层特点的倾斜率“控制标准”。基于提出的模型与计算，对于超高层建筑，采用最大倾斜率控制的安全系数小于采用节点不平衡力相对容差控制的安全系数；对于破碎基岩地层，基于HoekBrown模型的强度折减法计算的安全系数略小于只折减结构面强度的安全系数。项目案例可为基岩地区超高层建筑的稳定性分析提供借鉴。

Abstract: Based on the numerical analysis of a 380m super-high-rise building on the fractured bedrock, the strength reduction method, the load increasing method and the joint strength reduction method for the stability analysis of the foundation on the bedrock are proposed. One failure criterion is proposed based on multiple elastoplastic solvers and the tolerance of unbalanced force on the nodes, while another criterion based on the inclination of the foundation is also discussed. Based on the numerical model and results, for the super-high-rise building, the factor of safety controlled by the inclination of the foundation was smaller than that controlled by the tolerance of unbalanced force. For the fractured rock, the factor of safety calculated by the strength reduction method with Howk-Brown criteria was smaller than that calculated by the joint strength reduction method. The case in this paper may provide valuable experience for the stability analysis of the super-high-rise building on the rock.
