摘要
本文阐述在断裂构造地质地带的公路定线问题。包括:用航空象片判释和地质调绘方法查明断裂构造分布情况,用航测成图和纸上定线方法确定路基和桥隧构造物的稳定位置。结果表明:用航片判释区域地质构造有较好效果,通过地质调绘为评价路线方案和确定线位提供可靠依据,通过航测成图和纸上定线作出了比较经济合理的方案。
This paper investigates the highway alignment in the fault structural zone. The distribution of the fault structures was found out by the methods of aerophotograph interpretation and geological survey. The stable locations of the subgrade, the bridge and the tunnel were laid out by photoplotting and paper locating. The results obtained show that the regional geological structure can be interpreted effectively by aerophotograph and a reliable basis for the evaluation of the proposed alignment and location can be provided by geological survey. By aerophotoplotting and paper locating an economical and reasonable scheme is obtained.
