摘要
介绍了一种通过电阻率测量来对钢筋混凝土结构腐蚀损伤进行检测的新无损检测方法--电阻率测量的四探针法.讨论了这种方法在实际测量中的截面尺寸效应对电阻率的影响,从理论上推得了这种尺寸效应的修正公式.其计算结果与实验数据能较好吻合.
A new nondestructive evaluation technique for detecting corrosion of reinforced concrete structures by measurement of resistivi- ty, namely the four - point probe method of measuring resistivity is introduced. The effect of section dimensions on resistivity measurement is discussed. The correction divisor of the effect of dimensions is obtained. The calculation results quite agree with the test data.
