评估预应力混凝土结构中混凝土的应力状态对于施工管理和运维都是非常重要的。利用莫尔条纹原理研制了一种应变可视化贴片，它可以用肉眼直接读取混凝土表面的近似应变值，还可以用数码相机等远程、非接触、高精度地测量应变。本文介绍了研制的应变可视化贴片的概况和性能验证结果。
Evaluation of the stress state of concrete in prestressed concrete (PC) structures is extremely important for construction management and O&M (operation and maintenance). We developed a strain visualization sticker using the principle of Moiré fringes, which makes it possible to read the approximate strain value of a concrete surface directly with the naked eye and also enables remote, noncontact measurement of strain with high accuracy by a digital camera, etc. This paper presents an outline of the developed strain visualization sticker and the results of verification of its performance.
