摘要
对丹山独塔斜拉桥进行了详细的外观调查,得出了基于外观调查的桥梁技术状况初步评定结果;在静载试验基础上,对桥梁结构及主要部件强度、刚度进行分析评定;通过动载试验,分析评估了大桥的动力性能;最后综合考虑各因素得出大桥综合技术状况评估结论.该方法实用可靠,具有一定的工程价值.
By means of apparent survey for Dan-shan Bridge, the preliminary evaluation is educed. Based on static and dynamic load tests, the intensity, rigidity and dynamic properties of bridge are analyzed and evaluated. Finally, the composite evaluation of bridge technical capability is defined. This method is practical and reliable, and it has definite engineering value.
