摘要
用超声脉冲法进行混凝土结合面质量检测时,规范推荐使用对测法和斜测法,但测试时经常遇见只有一个测试面的情况,不得不将换能器布置在试件的同一个侧面上进行超声平测。从某一混凝土梁施工结合面质量检测实例,采用超声平测与斜测法进行对比分析,结果表明:采用超声平测法检测混凝土结合面质量是可行的。
During inspection of concrete jointing surface quality, usually only one side can be used as testing plate. So we have to layoutsensors on the same plate. To comparative analysis of inspection of concrete jointing surface quality by ultrasonic penetration testing and plane testing in a instance,the results show that one-plate method can be utilized to detect concrete jointing surface quality.
