摘　　要：跨海通道是由大型结构,如桥梁、隧道以及人工岛,或由这些结构组合而成的大型工程项目。在项目开发期间,至关重要的是确定最佳结构形状及其组合方式,以便以最小的施工成本提供所需交通运力。为此开发了FAUST方法以考虑和优化跨海通道各种结构的结构性能。该方法分析了不同的结构类型,评估了每种跨海通道组合方式的最终施工总成本。基于结构几何形状与结构特征变化对结构进行优化,采用最经济可行方案标准,通过比较其造价,以此评估各种跨海通道方案。该方法在厄勒海峡跨海通道的应用实例中显示出了良好的结果。Strait crossings are large projects that nowadays consist of large structures as single bridges,tunnels and artificial islands or their combination. During project development it is important to define the optimal structural shape and combination that will provide required traffic capacity with minimum construction costs. The method FAUST has been developed considering and optimizing structural capacity of structures within the strait crossing. It analyses different structural types and evaluates the overall final construction costs of each crossing combination. Optimization of structures is based on variation of geometrical and structural characteristics of structures. The evaluation of different crossing options is based on comparison of their construction prices using criteria of economically most feasible solution. The examples of application are showing good results that are corresponding with results of constructed strait crossings shown here on the example of Oresund strait crossing.
