应用水电效应法对珠海大桥桩基础进行了普遍检测，使大桥隐蔽工程的质量得到了有效控制。该法使用方便、速度快、无损桩身，既能检测桩的完整性又能测定桩的承载力，并可判断桩的缺陷位置及混凝土的浇注质量。水电效应法特别适用于大直径和深水中的桩基检测。
Hydropower effect method is applied to test the pile foundation of Zhuhai Bridge widely, so that the quality of concealed bridge project is effectively controlled. The method is easy to use, fast, non-destructive pile body, both to detect the integrity of the pile and can measure the bearing capacity of the pile, and can determine the position of the pile defects and concrete casting quality. Hydroelectric effect method is especially suitable for pile foundation inspection in large diameter and deep water.
