静载试验检测技术在简支T梁结构中的应用

Application of Static Load Test Technology in Simply Supported T-Beam Structure

在高等级公路建设实践中,为了保证役高等级公路中预应力简支混凝土T梁的长期、健康运营,必须定期开展试验检测工作,以定量判定桥梁服役现状。本文以预应力简支混凝土T梁为研究对象,就试验检测中常用的基础检测和静荷载检测技术进行了深入分析,明确了上述试验检测技术的应用标准、检测流程及结果评价。

In the practice of high-grade highway construction,in order to ensure the long-term and healthy operation of the prestressed simply supported concrete T-beam in the service of high-grade highway,it is necessary to carry out regular test and detection work to determine the service status of the bridge quantitatively.In this paper,the prestressed simply supported concrete T-beam is taken as the research object,and the common foundation in the test and detection is discussed.The detection and static load detection technology are analyzed in depth,and the application standard,detection process and result evaluation of the above test and detection technology are clarified.
