| Abstract: | Stress wave reflection method is widely used in low-strain method of testing foundation pile shaft quality at present, it has some peculiarities such as convenient test, fast speed, easily interpretating measurement waveform etc. But the question between defect directivity and uncertainty of test results exists. Research on the effects of defect directivity in stress wave reflection method on measurement waveform can help to improve the construction quality. |
