走廊带方案比选在高速公路选线中的应用

Application of Corridor Belt Scheme to Compare and Select in Selection of Expressway Line

在高速公路项目建设中,公路选线是走在各专业之前的首要工作。路线方案的选择会直接影响项目建设的标准和工程造价等,需根据所拟建公路的等级、各控制点等确定路线走向。随着经济的发展,环境保护、水资源保护、文物保护等问题逐渐成为批复工程可行性研究重点考虑的因素。以庄浪至天水高速公路社棠至G30连霍高速接线路线方案为例,对2个走廊带方案进行方案比选,得出了毛雨河走廊带为推荐方案,并可为后续甘肃陇东复杂山区公路建设时路线比选提供参考。

The selection of highway route is the first job before every major in the construction of expressway project. The selection of route scheme should directly affect the construction standards and engineering costs of a project, and should be based the determined route alignment of the grade of the proposed highway and its every control point. With the economic development, the issues of environmental protection, water resource protection and historic preservation gradually become the key considerations for the reply on the engineering facilities study. Taking the connection route scheme of the Zhuanglang to Tianshui Expressway and the Shetang to G30 Lianhuo Expressway as an example, high-speed wiring route program as an example, two corridor belt schemes are compared and selected. The Maoyu River Corridor Belt is determined as the recommended scheme, which can be referred for the route comparison and selection of highway construction in the complex mountainous area in the east of Gansu.
