摘　　要：针对山区复杂地形下高速公路布线的多方案选择问题,拟定数个能贴切描述地形纵、横向起伏变化的指标,以已有的优秀山区高速公路路线方案为依托采集样本数据,并对其进行判别分析,最终建立并标定了山区高速公路路线设计中路基和桥梁方案的判别模型.通过把模型应用到其他已设计的优秀山区高速公路路线方案上,得到与实际方案相一致的判别结果.Aiming at the multiple plan choice of alignment arrangement for expressway in complicated mountainous terrain, some indexes describing the terrain fluctuation of vertical and cross section were studied. Based on well-designed mountainous expressway alignment plans, sample datum were collected, distinguished and analyzed, and finally the distinguishing models of subgrades and bridges plan were established and calibrated. By applying the models to other well-designed mountainous expressway alignment, the distinguishing results obtained by the models corresponded with the actual plans.
