基桩浅部缺陷检测的理论与工程实践

The Test Theory and Practice of the Severe Faults in the Upper Parts of the Pile

在瞬态激振作用下,缺陷以上桩体表现为刚体阻尼振动,一维杆弹性波动理论不再满足,结合工程实践,分析了当基桩存在浅部缺陷时其低应变实测曲线的特征。

The mathematical model of the vibration about the upper severe faults in a pile is put forward based on theoretical nalysis, and the curve characters of low strain test is described according to its engineering practice.
