广元市射箭桥检测试验研究

为了检验射箭桥的设计和施工质量,确定工程的可靠性,同时了解桥梁的受力性能,判断桥梁实际承载能力,评价桥跨结构在设计荷载下的工作性能,需要对该桥梁进行检测。对射箭桥进行了混凝土强度及静、动载试验研究,将现场实测的数据与专业软件计算出的数据进行对比分析。试验结果表明,射箭桥满足公路-I级、人群荷载3.5 k N/m2设计荷载等级要求。

Researches on the detection of Shejian bridge in Guangyuan city

To test the Shejian bridge＇s design and construction quality,determine the reliability of engineering,understand the mechanical properties of the bridge,judge the actual bearing capacity of bridge and performance evaluation of bridge structure under the design load,it was necessary to detect the bridge. We have successfully studied the concrete strength,static load test,dynamic test of Shejian bridge. Combining with the measured data and professional calculated data,the measured value is compared with the theoretical solution. It is proved that after the detection,the Shejian bridge meet the design load requirements of highway-I grade,3. 5 k N / m^2 crowd load.
