钢筋混凝土结构裂缝深度无损检测技术的现状及发展

钢筋混凝结构在建设及运营过程中会由于多种原因出现裂缝。裂缝的位置、尺寸,尤其是裂缝的深度是判断裂缝对结构安全性影响程度的重要指标。近年来裂缝深度的无损检测技术有了长足进步,但其测试精度和探测深度仍然不理想。对目前裂缝深度无损测试技术进行了对比,并提出裂缝测试技术的进一步研究方向。

Present Situation and Development of Nondestructive Testing Technology on Reinforced Concrete Structure Crack Depth

The cracks in reinforced concrete structure are caused by many reasons in construction and operation process.The location and size,especially the depth of cracks is the most important index to judge the safety degree of structure.In recent years,the depth of the cracks in nondestructive testing technology has made great progress,but its testing accuracy and probing depth remains insufficient.Therefore,the depth of the crack nondestructive testing techniques are compared,and the further trend of the research is proposed.
