| 摘 要： | 低应变反射波法就是量测桩身阻抗Z变化的应力波反射规律。根据测得的入射波和反射波的波形、相位、振幅、频率及波到达时间等特征,推定单桩桩身完整性。根据基桩动测的一般原则,分析现场测试记录,可将基桩质量分为4类。通过几年来的工程实践,总结出低应变反射波法的优点。

| Abstract: | Low strain reflected wave method is to measure changes in the pile impedance Z reflection of stress waves.According to the characteristics of waveform,phase,amplitude,frequency and wave arrival time of measured the incident waves and the reflected wave,presumes integrity of single pile body.According to the general principles of piles of dynamic testing,analyses field testing records,pile-quality can be divided into four categories.Through the engineering practice for several years,sums up the advantages of... |
