摘要
通过对某大跨径斜拉桥混凝土索塔在温度、收缩作用下的数值仿真计算,结合现场实测数据分析,探索桥塔混凝土施工期间在变形荷载作用下的开裂机理,提出类似混凝土结构裂缝控制的构造处理措施和施工措施。
Based on numerical emulation computation for concrete cable tower of a large-span cable-stayed bridge tinder effect of temperature and shrinkage in combination with analysis for measured data on site, this paper searches after the cracking mechanism of bridge tower concrete under deformed load during construction and proposes structure treatment and construction measures for control of structural cracks of similar concrete.
