摘　　要：为了实现对艰险山区铁路桥隧工程技术接口关键要素的协调优化控制,将多属性效用函数与“三一”要素转化结构结合,构建技术接口的关键要素均衡优化模型.分析质量、进度、成本、安全要素间的关系,将它们的关联性以函数形式量化,并利用“三一”要素转化结构确定关键要素间的“主附”维度,构建艰险山区铁路桥隧工程技术接口的关键要素均衡优化目标函数.基于技术接口对关键要素的作用机理,利用ANP确定均衡优化函数的决策偏好系数,采用基于偏好向量引导的高维目标协同进化算法(ASF-PICEA-g)求得均衡优化模型的最优解,并在整体模型的最优解下得到各关键要素的较优解.以藏木特大桥与安拉隧道为例,对其技术接口构建均衡优化函数并进行优化分析,结果验证了构建的均衡优化函数的合理性以及ASF-PICEA-g在求解该模型方面的有效性.In order to collaboratively and optimally control the key elements of the technical interface of the railway bridge-tunnel in the arduous mountainous area,the tradeoff optimization model of the key elements for the technical interface was established,which was combined the multi-attribute utility function and the"three-one"elements transformation structure.Firstly,the relationships among quality,schedule,cost and safety were analyzed and quantified by functional forms.The"three-one"elements transformation structure was employed to determine the"main attachment"dimensions,and the tradeoff optimization function of the key elements for the technical interface of the railway bridge-tunnel in the arduous mountainous area was established.Then based on the mechanism that the technical interface to the key elements,the decision preference coefficients of the tradeoff optimization function were determined by ANP,the achievement scalarizing functions preference inspired co-evolutionary algorithm(ASF-PICEA-g)was used to obtain the optimal solution of the tradeoff optimization model,and find the optimal solution of each key element under the optimal solution of the whole model.Finally,both the rationality of the tradeoff optimization function and the effectiveness of the ASF-PICEA-g were verified by constructing the tradeoff optimization function of the technical interface between the Zangmu Bridge and the Allah Tunnel and carrying out the optimization analysis.
