摘要
桥梁静载试验是分析桥梁静力特性的重要手段.阐述了桥梁静载试验的加载原则、加载方案设计和测点布置规则.通过对大跨径连续箱型梁桥静载试验研究,分析了大跨径连续箱型梁桥在设计荷载作用下的承载能力、挠度特性和应变特性.试验结果分析表明:在设计荷载作用下该箱型梁桥的强度、刚度和抗裂度满足桥梁设计要求.
Static test is an important measure for static behavior of bridges. The loading principle, loading project and rule of measuring-point arrangement for bridge static test are presented. Based on static test research , load-bearing capacity is analyzed as well as the flexivity behavior and the strain behavior of a long-span continuous box-girder bridge under design-load with static test. According to the analysis, the strength, the rigidity and the anti-crack of the bridge meet relative criterions of bridges.
