锚碇是支承主缆、保证桥梁主体结构受力稳定的重要部位，为保证桥梁安全，锚碇应具有足够的稳定性和力学特性。签于锚碇在悬索桥中的重要性，以重庆长寿长江二桥北锚碇基础为例，通过验算其稳定性以及利用Abaqus3 D进行数值模拟，分析锚碇各施工阶段下的应力状态。结果表明锚碇基础稳定性和压应力满足要求，局部地方出现应力集中和拉应力，应对其进行设计优化处理。锚碇基础的验算和分析结果为重力式混凝土锚碇的合理设计和施工提供有益的参考依据。%The anchorage is the essential part of supporting the main cable to ensure the stability of the whole structure of the main bridge. In order to ensure the safety of bridges, anchor should have enough stability and mechanical properties. In view of the importance to anchor in suspension bridge, this paper analyze the an-chorage stress state of each construction stage based on the North Anchorage of the Second Bridge of Chang-shou Yangtze River in Chongqing and through the calculation of its stability and numerical simulation by using Abaqus3D. Examples show that the anchorage stability and compressive stress meet the requirements, but the locals appear stress concentration and stress, which should carry out the design optimization. The calculation and analysis of the anchor provides useful reference for reasonable design and construction for anchorage with gravity concrete.
