摘　　要：介绍重庆合璧津高速公路油溪长江大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,并采用三维实体有限元方法对锚碇结构进行应力分析,且基于计算和分析结果对锚碇整体和局部设计提出优化和改进措施。The key structural design of gravity anchorage of Youxi Yangtze River Bridge for ChongqingHebijin Expressway was introduced, with the overall stability of the structure and the stress on thefoundation calculated based on static method. Then the 3D solid finite element method was adopted tocarry out stress analysis on anchorage, and optimization measures for the overall and local design of theanchorage based on the calculation and analysis results were proposed.
