混凝土斜拉桥双箱梁桥面板模型试验研究与分析

Analysis and study on model experiment of double box girder of PC cable-stayed bridge

根据某斜拉桥的有机玻璃节段缩尺模型试验,分析双箱梁桥面板的受力及其有效工作宽度。通过对桥面板的实测有效工作宽度与一些国家的规范值进行比较,发现边箱桥面板的实测有效工作宽度接近于英国和德国规范值,而边箱之间桥面板的有效工作宽度接近于美国规范值。

According to an organic glass reduced scale model experiment of cable - stayed bridge, this paper studies the internal force and effective work width of double box girder. Comparing the measured effective work width with the thresholds of some countries＇ standards, we found that the effective work width of the bridge deck slab of the side boxes is close to the standard thresholds of U. K and Germany, while the effective work width of the bridge deck slab between two side boxes is close to the standard threshold of U. S.A. This conclusion can be helpful for simplifying the design of this kind of bridge deck.
