摘要
本文以纵波在杆中传播的理论为根据 ,介绍一种用于确定反射波往返时及视反射系数等参数的方法。将视反射系数经过一定的校正后 ,可定量分析反射界面的波阻抗差异的大小 ,进而确定桩身缺陷的严重程度 ;
Based on the propagation theory of the longitudinal wave in the pile, the present paper presents a technique for determining such parameters as back and forth time of reflection wave and apparent reflection coefficient. After some correction of the apparent reflection coefficient, the extent of wave impedance differences of the reflection interfaces can be analysed quantitatively and, on such a basis, the defective position of the pile body can be detected.
