高层建筑岩石边坡地基稳定性分析方法研究

Study on Analysis Methods for Rock Slope FoundationStability of the Highrise Building

通过工程实例对高层建筑岩石边坡地基稳定性分析方法－规范传递系数法、转动极限平衡法（瑞典条分法）及有限元法进行了研究，发现规范传递系数法所得安全系数较转动极限平衡所得安全系数大，而转动极限平衡所得结果接近有限元法。建议Ｄ对高层建筑岩石边坡地基进行稳定性分析时进行转动极限平衡校核。

Based on the practical project a study on analysis methods for rock slope foundation stability of highrise-building project criterion transfer coefficient method, rotation limit equilibrium method (Sweden slices method) and finite element method was carried out.The authors found that safety factor of criterion transfer coefficient method is larger than that of rotation limit equilibrium method, but is similar to the results of finite element method. So, when rockslope foundation stability of highrise building is to be analysed,the rotation limit equilibrium method is suggested to use.
