摘要
基于600 m深圳平安大厦最大直径8.0 m,扩底9.5 m的超大直径嵌岩桩承载力进行了数值分析计算,考虑桩周岩层差异性、桩-岩相互作用和桩端爆破施工工艺、岩体参数的影响,建立了超大直径嵌岩桩承载力数值计算模型,现场实测结果对比验证了数值计算结果的合理性。有关结果为类似工程提供参考。
This study is based on the bearing capacity of a 600-meter super-large-diameter rock-socketed pile with a max diameter of 8.0 m and a bottom expansion of 9.5 m.Numerical analysis and calculations were carried out,taking into account the influence of the difference between the rock layers around the pile,the pile-rock interaction,the blasting construction technique at the pile end,and the rock mass parameters.The accurate of the numerical calculation results is compared with site measurement.The results provide a reference for similar projects.
