| 摘 要： | 工程施工中混凝土强度检测一般通过两种方式检测，一种是取芯试压，此种方式可直接反应混凝凝土的真实强度。但对混凝土结构会造成一定程度破坏，或因构件含筋率较高，不易取出完整的素混凝土芯样，操作起来有一定的难度；另一种方式是采用现场回弹，此种方法常因仪器或操作人员操作方式不当影响混凝土回弹数值的准确性，只能作为混凝土强度值参考指标。本文通过介绍南广高铁混凝土现浇梁采用回弹超声波检测综合法的检测方式，能真实检测混凝土实体的强度值。

| Abstract: | Construction concrete strength testing is generally detected two ways, One kind is coring pressure test,this way direct response to the real strength of the coagulation concrete, but the concrete structure will cause a certain degree of damage, Or components containing a higher gluten rate, it＇s not easy to remove the complete plain concrete core samples, it has a difficult for operating; another way is using site springback, this method is often due to the mode of operation of the equipment or operating personnel improperly influence the accuracy of the values of the concrete rebound, Only as a reference index of concrete strength values. This article describes Nanning Guangzhou High Speed Rail situ concrete beams rebound ultrasonic inspection method of detection that can truly detect the value of the strength of the concrete entities. |
