以桥梁设计理论、有限元法分析技术为理论基础,对国内一座部分斜拉桥的静载试验进行了研究。通过实测值与理论值比较分析,结果表明该桥在试验荷载作用下主梁实测最大挠度值、塔顶最大水平位移值、最大索力值和最大应变值均小于理论计算值,在各个工况荷载作用下,实测残余挠度值与残余应变值较小,表明结构具有良好的变形恢复能力,桥梁结构性能良好。本次试验可为同类桥梁结构的设计和检测评估提供有价值的参考。

Base on the bridge design and finite element analysis theory, research on the static load tests of a partial cable -stayed bridges in china has been conducted by comparing the theory value with the measured value. The result shows that all of the maximum deflection of the girder, the maximum horizontal displacement on the bridge tower top, the maximum cable tension and the maximum strain of the girder measured under test load are smaller than the theory values, while in every loading working conditions, the measured residual deformation and strain are quite small, which indicates good deformation recovery capability of the structure, as well as good bridge structural performance. The static loading tests can provide valuable references for the similar bridge design and bridge inspection assessment.
