0　前言高应变动力试桩法是目前国内应用较广的一种桩基质量检测方法。它不仅可以提供桩的承载能力,而且还可以检测桩的完整性。由于采用数吨锤锤击,同时又实测了桩顶的力信号和速度信号,因此,其实测数据具有很高的信噪比。本文仅就高应变动力试桩法在预应力管桩的完整性检测方 0 Introduction The high-strain dynamic test pile method is currently a widely used method of quality inspection of pile foundations. It can not only provide the bearing capacity of the pile but also the integrity of the pile. Due to the use of several tons of hammer hammers, and at the same time measured the force signal and velocity signal at the top of the pile, the measured data has a high signal-to-noise ratio. This article only examines the integrity of prestressed pipe piles with high-strain dynamic test piles.
