摘要
用超声脉冲法进行混凝土工程强度或缺陷检测时,经常遇见试件只有一个测试面的情况,这时就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.针对超声脉冲平测法进行了分析研究,结果表明:采用超声平测法修正声速取代对测法声速后,可按常规公式推定混凝土强度;平测法相对于对穿法具有较强的可操作性;在混凝土缺陷探测时,可利用部分平测数据参与评定.
During testing concrete strength and damage, usually only one side can be used as testing plate. So we have to layout sensors on the same plate. Taking advantage of two engineering, the paper analyzes the pulsed ultrasound oneplate method. The result presents" After revising velocity of wave by ultrasound one-plate method, we can deduce concrete strength; One-plate method is more feasible than opposite-plate method; The partial results of one-plate method can be utilized to detect concrete damage.
