In order to investigate the corrosion state of reinforced concrete structures by non-destructive method, the method of resistivity measurement in the concrete material was adopted. In the present research, it is clear that the resitivity was decreased in case the reinforced bars were under concrete surface measured. Moreover, Dipole-Dipole method is appropriate for the case that electrode array is perpendicular to the direction of bar arrangement. On the other hand, Wenner method is well applied to the parallel direction of bar arrangement against the ekctrode array.

为了用无损方法研究钢筋混凝土结构的腐蚀状态，采用了混凝土材料中电阻率测量的方法。在目前的研究中，很明显，当钢筋位于混凝土表面以下时，其电阻率会降低。此外，偶极-偶极法适用于电极阵列垂直于棒材排列方向的情况。另一方面，Wenner方法很好地应用于与电极阵列平行的棒排列方向。
