应力波法基桩检测中复杂地层等效转换

Equivalent transformation of complicated layer for pile test with stress wave

利用应力波法一维线性杆状体理论推导得到的反射系数 K ,结合不同工程地质条件的波阻抗差异 ,分析了复杂地质条件对基桩检测的影响 ,并假设在基桩完整的条件下 ,提出了复杂地层等效转换的基桩模型 。

With the wave impedance difference of different engineering geological conditions, this paper, with the reflect coefficient K deduced from the theory of stress wave one dimension linear bar, analyses the influence of complicated geological conditions on pile test. Also an equivalent transformation pile model of complicated layer is presented under the hypothesis that pile is complete. At last, an example is used to explain the presented method.
