施工工艺对灌注桩承载力影响的分析

On effect of construction technique to loading capacity of pile

通过理论计算,认为可以通过考虑Δ,μ和α值来确定施工工艺对灌注桩承载力的影响,同时,讨论了非挤土、部分挤土和挤土成孔法下的桩侧端阻力和端阻力,以期为类似工程设计与施工积累经验。

Through theory calculation, the paper thinks we could make sure effect of construction technique to loading capacity of pile through assuring value of △,μ and α. At the same time, the paper discusses about lateral tip resistance and tip resistance under the construction of non squeezing, part squeezing soil pore, and squeezing soil pore, it aims to accumulate experiences for such kind of construction.
