岩溶地区冲孔灌注桩设计,由于地质条件复杂,增加了对桩身完整性检测的难度。通过实际工程,分析探讨各种检测方法的特点、适用范围和局限性,提出低应变法、超声波投射法和钻芯法综合运用模式,针对不同工况灵活采用不同检测方法组合的模式,提高了检测精度,加快检测进度,降低检测费用,可为类似工程提供参考依据。
Perforated cast-in-situ piles design in karst area, due to the complex geological conditions, increases the difficulty of testing the integrity of pile body. Through the actual project, the characteristics, applicable scope and limitations of various detection methods are analyzed and discussed. The low strain method, ultrasonic projection method and integrated core drilling method are put forward. The flexible combination of different detection methods for different working conditions is proposed, Testing accuracy, speed up the testing progress, reduce testing costs, can provide a reference for similar projects.
