混凝土单桩竖向承载力的试验分析

Experiment Analysis on the Influence of Concrete Impregnate Pile to the Single Pile Vertical Load Capacity

通过对同场地同地质条件下 ,相同桩径与桩长的潜水钻成孔灌注桩和冲击钻成孔灌注桩的工程静载试验 ,给出这两种成桩工艺的单桩竖向抗压极限承载力。在比较分析的基础上 ,指明导致潜水钻成孔灌注桩承载力较低的原因。可供建筑桩基设计及施工借鉴。

It describes a engineering steady load test of same diameter and length impreguate pile drilled respectively by dive drilling bit and cable drilling bit under the same geology condition and at the same site,shows the single pile vertical resistance pressure limit load capacity of the two different pour technology.Based on the comparing and analysis,it points out the reason of lower load capacity of dive drilling hole pile.This result can be uscd for reference by pile foundation dcsign and construction.
