介绍了电容成像技术在混凝土检测中的应用。采用二维有限元方法模拟了电容式成像探头的电场分布及其与混凝土样品的相互作用。利用原型电容式成像探针进行了物理实验。概念验证结果表明，电容成像技术可以用于检测混凝土样品表面的裂缝，以及表面下的空气空洞和钢筋。(C) 2010 Elsevier Ltd.版权所有。
This paper describes the application of capacitive imaging to the inspection of concrete. A two-dimensional finite-element method was employed to model the electric field distribution from capacitive imaging probe, and how it interacts with concrete samples. Physical experiments with prototype capacitive imaging probes were also carried out. The proof-of-concept results indicated that the capacitive imaging technique could be used to detect cracks on the surface of concrete samples, as well as sub-surface air voids and steel reinforcement bars.
