摘要
研究目的:向莆铁路长大隧道众多,在地面地质调查中存在地形高差大、地质构造复杂、植被发育、基岩露头少、勘察周期短、大面积地质测绘难等问题,难以快速准确地获取大比例尺区域工程地质信息。研究结论:基于研究多源地质资料信息化集成、三维可视化遥感影像建模和三维可视化遥感解译方法,建立了向莆铁路戴云山—高盖山段的线路、地貌、地质等三维场景,进行地貌特征、断裂构造和不良地质的定量解译。解译成果可有效指导地质调查,减少外业工作量,保证长大隧道大比例尺地质调查精度。
Research purposes ： Ground geological survey of Xiang - Pu Railway long tunnels face the problems of terrain level difference large, geological structure complexity, vegetation thick, bedrock outcrops lack, surveying cycle short, large area geological surveying and mapping difficulty, and it is difficult to quickly and accurately for large scale region engineering geological information. Research conclusions： Based on the study of muti - geological information integration, 3 D visualization remote sensing image modeling and 3D visualization remote sensing image interpretation method to establish route, physiognomy and geology 3D scene of DaiYun -shan to Gao Gai -shan Zone for qualitative interpretation of the morphological characteristics, fault structures and bad geology. Interpretation results can effectively guide geological survey, reduce the workload, ensure tunnel large scale geological survey precision.
