奉节新城碎石土地基承载力试验研究

Study on bearing capacity of debris foundation in new Fengjie city

通过对重庆市奉节新城某综合楼地基碎石土层桩端承载力试验与研究,分析了奉节新城碎石土层的力学性质,阐明了原位试验的必要性,避免了因基础勘察不详存在的安全隐患,提出了桩端碎石土验槽方法。

Based on the test of end-bearing capacity of piles in debris foundation of a building in Fengjie, the paper analyses the physical character of debris foundation and demonstrates the necessity of performing prototype test, by which one can avoid the hidden danger from undetailed foundation investigation. Herefrom the method for detecting the bearing capacity of a debris foundation is also proposed.
