摘　　要：通过对北京—新疆高速公路临河至白疙瘩标段进行勘察,并从区域地质、地形地貌与技术经济指标三个方面对K线与各个对比线做出评价,研究发现:工程区域自然环境恶劣,地下水总体比较贫乏,区域地形呈南高北低状,地貌类型主要为戈壁、荒漠草原;京新高速公路各段K线与对比线区域地质条件接近,但从地形上看路井西至白疙瘩段B4线地形起伏较大,路井西至上盐池段B4+B3线地形起伏较大;京新高速公路各段K线与对比线各项技术经济指标大小均接近,其中仅有额济纳旗过境段(K线与A3线)的桥梁长度、排水及防护数量与路面面积,查干淖尔至呼鲁逊呼都格段(K线与B1线)的桥梁长度,K线的数量大于对比线,K线建安费比对比线小,因此推荐K线方案。此研究可为同类高速公路选线工程提供参考。The Beijing-Xinjiang Expressway is an important part of the Beijing-Urumqi Expressway(G7)of the national expressway network,which runs from the river to Baiyue(Mengganjie).In this paper,through the investigation of the Beijing-new expressway from the river to Baihe(Mongolia-Gansu zone)section,and from three aspects of regional geology,topography and geomorphology and technical and economic indicators to evaluate the K line and each contrast line,it is found that:the project area natural environment is bad,the groundwater is relatively poor,the regional terrain is high in the south and low in the north,the landform types are mainly Gobi,desert steppe;The regional geological conditions of line K and contrast line are close to each section of the Beijing-new Expressway,but the topography of line B4 from the west of Lujing to Baihe section is relatively large,and line B4+B3 from the west of Lujing to the upper Yanchi section is relatively large.All the technical and economic indexes of Line K and contrast line are close to each other,among which only the bridge length,drainage and protection quantity and pavement area of Ejin Banner transit section(Line K and A3),the bridge length of Chaganzhur to Hulusun Huduge section(Line K and line B1),the number of line K is larger than the contrast line,and the construction and installation cost of line K is smaller than the contrast line.Therefore,it is recommended that the plan of line K is the best choice for the section from River Linhe to Baiyue(Mengganjie)of Beijing-new Expressway,which can be used as a reference for the future study of highway route selection scheme.
