超声脉冲法裂缝深度检测分析

Ultrasonic Pulse Method Crack Depth Detection

用超声波脉冲法检测混凝土裂缝的深度,具有简单、快速、准确和不破坏原结构物的优点。在公路工程施工中,桥隧和路面等工程的混凝土结构实体,常因各种原因产生不同程度的裂缝。由于裂缝的存在使结构物的整体性和耐久性性能有不同程度的降低,甚至危害建筑物结构的安全和使用。为了确定混凝土裂缝的危害程度以及制定补救措施,常常需要首先确定裂缝深度、长度、宽度以及裂缝中是否有其它填充介质等等指标,尤其是裂缝的深度指标的测定、超声波脉冲法提供了一种方便的检测手段。

Depth method detection of cracks in concrete by ultrasonic pulse, has the advantages of simple, rapid, accurate and does not destroy the original structure.In road construction, bridge and tunnel concrete structure entity and pavement engineering, often for a variety of reasons for different degrees of cracks. Due to the presence of fracture structure integrity and durability performance decreased to different extent, and even endanger the safety and use of building structure. In order to determine the extent of hazards of concrete cracks and the formulation of remedial measures, often need to first determine the length, width and depth of cracks, cracks in the filling medium and so on whether there are other indicators, especially the determination of ultrasonic pulse method, crack depth indicators provide a convenient means of detection.
