摘要
文章以某高层建筑灌注桩桩基完整性检测为例,对比分析了低应变反射波法与声波透射法在灌注桩桩身完整性检测中的应用。研究表明,低应变反射波法具有快速、经济、便于普查的优点,而声波透射法能够精确识别缺陷位置与性质,二者具有较强的互补性。通过现场开挖验证,两种方法的检测结果一致,均可较好地判断桩身缺陷位置,证实其在桩身完整性检测中的可靠性与准确性。
Taking the integrity testing of cast-in-place pile foundation for a high-rise building as an example,this paper compares and analyzes the application of lowstrain reflected wave method and crosshole sonic logging in cast-in-place pile integrity testing.The research shows that the low-strain reflected wave method has advantages of rapidity,cost-effectiveness,and convenient census,while the crosshole sonic logging can precisely identify the location and properties of defects,and the two have strong complementarity.Through on-site excavation verification,the testing results of the two methods are consistent,and both can better determine the location of pile defects,confirming their reliability and accuracy in pile integrity testing.
