摘要
通过多年现场检测经验,总结出灌注桩钻芯取样过程的技术要点和异常情况的分析处理,为更加客观实效地判定桩身的完整性、混凝土强度、桩长、桩底沉渣厚度及持力层性状能否满足设计及规范的要求提供参考。
Based on the experience of the field detection for many years,the techniques points and solutions for abnormal situation that occurred during core drilling sampling process were summarized.It provided a better judge reference on the pile integrity,concrete strength,pile length,bottom sediment as well as bearing capacity could satisfy with the requirements on design and standards or not.
