采用纤维编织网增强混凝土进行砌体墙的加固，并利用数字图像相关技术（DIC）可以全场测量的特点，在全场范围内对加固砌体墙在承受荷载时所产生的裂纹扩展情况进行探测.探测结果表明：随着荷载的增加，砌体墙加固层持续开裂，由微裂纹逐渐形成肉眼可见的裂缝，裂缝的形态和扩展路径与应变场的变化相对应.
Textile reinforced concrete was used to reinforce the masonry walls. And the digital image correlation technology was used to observe the initiation and expansion of invisible cracks because of its characteristics of full-field measurement. The results show that the reinforcement layer of the specimen continues to crack and form visible cracks as the load increases. The shape and propagation path of the cracks correspond to the strain field.
