Research On The Test For The Strength Curve Line Of The Comprehensive Method Of Ultrasonic Elasticity In Bou Tou

Technology of Non-damage test for concrete intensity is extensively applied in project testing, as a precise and direct approach .Accordingly, the test in this essay makes use of average concrete samples made up of commo -n raw material in Boutou, and adopt comprehensive method of ultrasonic elasticity to test the concrete used within one year in Boutou. Through the regression analysis, we get the regression equation of anti-intensity of these two materials under the given conditions. According to the result, we establish the accurate curve line for comprehensive method of ultrasonic elasticity and provide practiced and Non - damage testing approach and calculating method for concrete intensity test and reference for testing staff concerned.To prove the applicability of respective regression equation , the essay adopt regression analysis to test the accordance of samples and find the testing report accords with the predicating one. To test the applicability and practical usage of the intensity curved line in Boutou, we test the concrete items on site, and compare it with standard curved line in my country, and the consequence shows that: the intensity curved line of the comprehensive method of ultrasonic elasticity has high applicability and accuracy.
