In this study, firstly, the most commonly used nondestructive testing technology, that is, ultrasonic nondestructive testing technology, is introduced. And the common testing methods are listed and the main influencing factors and precautions are analyzed. Secondly, the road and bridge engineering quality management methods and control measures are put forward, that is, develop a scientific quality management plan, improve the quality management awareness, and establish the construction quality management and control measures. The results show that this study can provide a reliable basis for taking measures in advance and formulating effective reinforcement plans for roads and bridges with hidden safety hazards and objectively determining whether roads and bridges need to be dismantled. Therefore, this study has a certain practical significance and provides a certain reference for the safe operation of current road and bridge projects.","PeriodicalId":444299,"journal":{"name":"Modern Civil and Structural Engineering","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122060930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
