多种检测方法在判断桩身缺陷过程中的综合应用

Comprehensive Application of Various Detection Methods in the Process of Judging Pile Defects

钻芯法作为桩身完整性检测中最直观的检测方法,在灌注桩桩身完整性检测时得到了广泛应用。但当钻芯法发现基桩桩身某深度离析或夹泥等缺陷时,只能检测出在钻芯法钻孔内沿深度方向的缺陷情况,并不能反映缺陷沿桩身横截面的横向展布情况。本文通过现场检测采用多种检测方法综合运用对桩身缺陷在横纵方向上的缺陷程度进行进一步的分析推测,取得了较为可靠的成果。

As the most direct method of pile integrity testing,core drilling method is widely used in the integrity testing of cast-in-place pile.However,when some depth segregation or mud inclusion is found in the core drilling method,the defects along the depth direction can only be detected in the core drilling method,and can not reflect the transverse distribution of the defects along the cross section of the pile body.In this paper,the degree of defect of pile body in horizontal and vertical direction is further analyzed and inferred by using many kinds of detection methods in the field,and reliable results are obtained.
