摘要
以某长江大桥为例,介绍悬索桥重力式锚碇的结构设计要点,采用静力学方法对结构的整体稳定性和地基应力进行详细计算以及三维实体有限元方法对锚碇结构进行应力分析,通过计算和分析结果对锚碇整体和局部设计提出了优化和改进的措施。
Taking a bridge of Changjiang River as an example, the article introduces the structural design gist of the gravity anchorage of suspension bridge. The statics method is used to calculate the overall stability and subgrade stress of structure in detail and the 3 D entity finite element method is used to analyze the stress of anchorage structure. Based on the calculation and analysis results, the measures of optimization and improvement are proposed for the overall and partial designs of anchorage.
