摘　　要：北京市山区旅游公路多为乡村公路等级,线路设计形式一般以路基为主,辅以少量小桥涵,无隧道,勘察阶段为一次性详细勘察。该类线路工程勘察应以区内的不良地质现象为勘察重点,在充分收集利用现有资料基础上,以工程地质测绘为主,以钻探为辅的原则来布置野外工作;事实证明,该方案取得了预期效果。此外,还提出了注意环境保护方面的建议。The tour highway within mountainous area of Beijing are mostly at grade of country road, which were currently designed in roadbed with a few bridge and culvert, without tunnel, and its survey phase is one trial detailed survey. The emphasis of the highway survey should be bad geological phenomenon and the principle of field work layout is that engineering geological mapping is prior to drilling. The facts show that the scheme has obtained expected result. Furthermore the paper also gives some suggestion for environmental protection.
