S207线 K216+000处，终点与马陇公路 K37+300处相接（即 2012 年拟建通（渭）陇（西）公路通渭县马营至陇西云田段公路建设工程榜罗支线 K24+100 处），路线全长 55.526km，利用拟建马陇路榜罗支线7.63Km 即到达榜罗革命遗址；另有通往温泉的支线一条，与主线 K7+995.57 处相接，长 4.6km， 终点至温泉桥头， 项目建设里程 60.126km。 拟建项目具体地理位置见图 1-1。 1.3建设性质 新建 、改扩建 1.4建设周期 本项目所在地正在根据西部大开发和国家扩大内需政策大力发展经济，对公路建设迫切需要，因此工程应早开工、早运营、早见效益，根据相关文件精神，本项目拟建议按如下计划安排实施： 2012年 10月底完成工程可行性研究报告； 2012年 7月底完成初步设计，开始项目招投标等前期准备工作； 根据主体工程设计报告，工程计划 2013 年开工，建设总工期 23 个月。 1.5 建设规模 根据甘肃省“十二五”旅游业发展规划，结合沿线乡镇社会经济和交通量发展预测和区域路网结构、等级的配置需求、“西部大开发”提 出的西部地区交通基础设施适当超前、加快建设的原则，以及甘肃省政府确定的公路交通建设实现跨越式发展的总体要求，同时根据公路工程技术标准中各等级公路远景设计年限的适应交通量范围，研究路段里程加权平均交通量超过 5000 辆 (折合小客车 )，按照以上有关对拟建公路的通行能力与交通适应性分析看出，本项目采2 图 1-1 拟建项目地理位置图 3 用推荐的建设标准完全可以满足未来设计年限的交通增长需求，推荐的建设标准不存在剩余。本项目推荐的公路建设规模、技术标准及附属配套工程如下： （ 1）主线 K0+000 K23+800段采用设计速度 60km/h的双向二车道二级公路技术标准，路基宽度为 10m，具体布置为：行车道（ 2× 3.5） m+硬路肩（ 2× 0.75）m +土路肩（ 2× 0.75） m =10m； 主线 K23+800 K55+526.1段及温泉支线地形相对复杂，如采用 60km/h的设计速度，将导致造价增加过大，同时产生大段的高填深挖路段，影响运营安全，并且对沿线脆弱的生态环境造成不必要的破坏，对沿线农田造成大量的侵占。经与项目建设相关单位多方比较论证，并充分考虑本项目的建设资金限制，拟采用设计速度 40km/h的双向二车道二 级公路技术标准，路基宽度为 8.5m，具体布置为：行车道（ 2× 3.5） m+土路肩（ 2× 0.75） m =8.5m。 （ 2）推荐方案全线长 60.126km。 （ 3）推荐方案全线设置平面交叉 15处。 （ 4）全线共设置大中桥 5座、高填土涵洞 6 道、涵洞 117道、通道桥 2座。桥涵设计汽车荷载等级、设计洪水频率、净空和抗震设防等按规范要求设置。此外为保证路基的安全和稳定，全线设置必要的防护排水等工程。 （ 5）全线配置完善的交通标志、标线、线性诱导标、轮廓标、护栏等安全设施。 （ 6）全线设置综合管理站 1处，主线收费站 1处。 （ 7）推荐方案全线红线设置为距离路基外 2m，部分路段根据地形予以适当调整。 拟建项目方案组成详见表 1-2。 4 表 1-2 项目组成一览表 项 目 单位 数 量 备注 主线 支线 合计 主体工程 路线长度 Km 55.526 4.6 60.126 土石方 万 m3 270.98 7.47 278.45 排水工程 万 m3 防护工程 万 m3 沥青路面 万 m2
