摘　　要：采用平测法布置超声波测点 ,先测得无损区混凝土的声波速度 ,再利用损伤区不同测点的声时和相应的平面测距 ,通过公式转换求得混凝土损伤层的厚度。该方法测试方便 ,计算简捷 ,实用性好。The thichness of a damaged concrete can be obtained by the following steps:A plane measurement is used to arrange sonic measuring points; the sonic velocity of the concrete within a nondestructive zone is measured first, and then sonic propagation time of different measuring points within a damaged zone and their corresponding plane measured distances are used,which can be transformed by formulas.This method features convenient testing,simple calculation and excellent practicality.
