钻芯法在冲孔灌注桩成桩质量检测中的应用

Core Drilling Method Used in Testing of Punching Hole Cast-in-place Piles

结合工程实践阐述了钻芯法在检测嵌岩冲孔灌注桩时需注意的事项。工程实践表明,钻芯法与低应变和高应变动测技术在对复杂地质条件下的桩基和问题桩检测中互为补充,能更准确地揭露桩基所存在的缺陷,避免采用动测技术时,由于桩基工程隐蔽性这一特点带来的误判,减少工程隐患。

The points for attention of core drilling method using in testing of cast-in-place piles are discussed by integrated with engineering practices. The engineering practices demonstrate that complimentarily of core drilling method and low strain integrity testing or high strain dynamic testing in testing of cast-in-place piles which are cast in strata of complex composition could reveal defects of cast-in-place piles more precision, revise our judgment of the defects and reduce potential dangers.
