| 摘 要： | 本文从几百例机械阻抗法测桩实例中,精选出具有代表性的病例进行剖析.从导纳曲线形状、特征、变形、导纳值N、动刚度K_d及波速值V_0等的变化规律,结合成桩方法、场地工程地质、水文地质条件等总结一套较成功的、对不同类型桩身损伤进行判识方法,并根据实测动刚度如何预估单桩承载力提出自己的看法.

| Abstract: | From several hundred case histories of the mechanical impedance method to test illcondi-tioned piles , representative cases are carefully chosen to be analyzed. From the variation law of the form , characteristics, deformation of the conductance curve, the conductance value N , the dynamic stiffness K, and the wave velocity V etc. combined with the method of pile making, the engineering geological and hy-drogeological conditions of the site, a set of relatively successful method of discriminating the damage of different type pile body is summarized, also the personal view of how to predict the single pile bearing capacity based on practically measured dynamic stiffness is presented . |
