部分斜拉桥横向应力试验及分析

Lateral Stress Test and Analysis of Partial Cable-stayed Bridge

通过对兰州市小西湖部分斜拉桥箱形梁模型的横向应力分布试验,得到箱形梁在有横隔板截面和无横隔板截面的应力分布,通过试验与理论计算的比较,研究了箱形梁横向应力分布的简化计算方法.

Through the test of lateral stress distribution of partial cablestayed bridge's model with the box beam of Xiaoxihu bridge in Lanzhou, by comparing analysis of the test data with the analysis of theoretic data the distribution of lateral stress of the box beam, which has respectively considered the diaphragm or not diaphragm, are further studied. The theoretic simplified calculated method is investigated.
