摘要
CFG桩复合地基桩、土发挥性状与基础刚度密切相关。刚性基础和柔性基础下CFG桩复合地基室内模型对比试验得出,在试验条件下,两者在桩土应力比,桩、土荷载分担比,桩、土承载力发挥,变形场和负摩擦区等性状方面存在明显差异。试验结果可为CFG桩复合地基在交通市政领域中的应用提供参考。
The character of CFG pile composite foundation is correlated with rigidity of foundation. Model tests of CFG pile composite foundation under the flexible and rigid foundation are carried out. Some useful experimental data is obtained through the study. The differences of pile-soil stress ratio, pile-soil load ratio, deformation, negative skin friction, etc., are analyzed. The experimental results can provide valuable preference for the application of CFG pile composite foundation to the field of traffic and civicism.
