摘要
低应变法广泛应用于桩身完整性检测,但各类具体缺陷引起的波阻抗变化存在很大模糊性,而波阻抗又是响应曲线波形的主要影响因素,从而使时程曲线的正确判读存在难度很大难度。以五种模拟桩所代表的具体缺陷特征对响应时程曲线的影响分析的基础上,总结相应的各种缺陷特征的低应变法检测判读技巧,具有一定的参考价值。
The low-strain method is used widely in examining the integrality of pile. The wave impedance is changed more hazily by the affection of each concrete disfigurement, and the wave impedance has the most effect on the response curve's flexuosity, so it is much difficult to judge accurately the response-time curve. Based on the analysis of each concrete disfigurement's affection which is one of the typical disfigurement in the five types simulated pile, the skill of judging accurately the response-time curve is summed up. Certainly, it has some reference significance.
