摘要 首先介绍了某自锚式独塔悬索-斜拉协作体系桥梁的概况、主缆线形、吊索和拉索索力测试,然后介绍了静载试验和试验结果,最后分析该类桥梁的自振频率和振动响应。分析结果表明:(1)主梁线形基本达到设计成桥线形的要求;(2)大部分斜拉索索力基本与设计索力值较为接近;(3)静动载试验结果表明,该桥满足设计荷载等级要求。 The basic situation of a self - anchored suspension and cable stayed cooperative system bridge with single tower was firstly introduced, as well as line style of main cable, eable toree of sling and dragline, and then the static load test and test results were also present, the modal frequencies and vibration response was analyzed. Results extraeted are listed as follnws: ( 1 ) Line type of main girder meets the requirement of design line style; (2) Test cable foree is close to the design one; (3) The results of static and dynamic test are shown that the bridge meets the design load class.
