耳墙式桥台扩大基础优化设计是《桥梁自动化设计》研究专題的一部分,也是《桥墩扩大基础优化设计》研究成果的继续。在数学模型的建立、优化方法的选用及加快收敛的措施等方面,本文与参考资料[1]基本相同。然而,桥台受力情况比桥墩复杂,设计变量与约束条件也较多,故程序也较复杂。 The earwall-type abutments to expand the basic optimization design is part of “Bridge Automation Design” research topic, but also the continuation of the research results of “Pier Foundation Design Optimization”. The establishment of mathematical models, the selection of optimization methods and measures to speed up the convergence and so on, this article and reference [1] basically the same. However, the abutment stress situation is more complex than the pier, the design variables and constraints are also more, so the program is more complicated.
