摘　　要：边界条件是高速公路选线的控制因素,边界条件的复杂性直接决定高速公路选线的难度。文中以贵州某高速公路城区段为例,为完成控制因素错综复杂的城区段公路选线工作,采用多方案比选论证的方法,阐述景区、铁路、公路、河道、管道、危岩体、堆积体共同制约的“五地物-两地质”耦合边界条件下的山区高速公路选线对策。分析各边界条件的特性及对高速公路建设的影响,针对性地提出相应的解决方案。并综合各边界条件的特性,提出具有可行性的3条路线方案,进行综合方案比选,择优推荐。研究以“五地物-两地质”复杂耦合边界条件下的某山区高速公路工程为实例,提出多边界条件影响下的山区高速公路选线方法。Boundary conditions are the controlling factors of route selection in expressway,and the complexity of boundary conditions directly determines the difficulty of expressway route selection.Taking the urban section of a certain expressway in Guizhou Province as an example,in order to complete the route selection work in the urban section with complicated control factors,the method of multi-scheme comparison is adopted.The route selection details of mountainous expressway under the coupling boundary condition of“five features and two geology”is demonstrated,which is jointly restricted by scenic spots,railways,highways,river channels,pipelines,dangerous rock masses and accumulation bodies.The characteristics of each boundary condition and its influence on expressway construction are analyzed,and corresponding solutions are proposed.Based on the characteristics of each boundary condition,three feasible route schemes are proposed,and the comprehensive scheme is compared and recommended.A case study of a mountainous expressway project under complex coupled boundary conditions of“five features and two geology”is conducted,and the route selection method of mountainous expressway under the influence of multiple boundary conditions is proposed.
