| 摘 要： | 利用应力波在一维杆中传播的机理对应力波在不同介面和变截面状态下的反射、透射与能量耗散之间的关系进行分析的基础上,用反射系数、透射系数、波幅衰减比等参数之间的关系及计算公式,对振动测桩中的实测波幅进行定量计算,得出面积削减率,以此值为依据进行桩身缺陷程度的判断.

| Abstract: | Quantitative calculation has been done for the measured wave width resulted from pole vibration measuring according to the correlation of reflection coefficient,penetrance coefficient and wave width weakening rate and calculation formulae on the basis of the analysis on the relationships between reflection,penetrance and energy dissipation of stress wave at different interface and variable cross sections using the mechanism of the traveling of stress wave in one dimension pole in order to got area reducing rate and the judgement of pile imperfection. |
