摘　　要：以瓦日铁路穿沂沭断裂带工程地质选线为例,提出重载铁路复杂断裂构造区选线原则和以遥感构造解译为先导的地质选线方法。根据踏勘、初测阶段的选线要求,选择不同层次的遥感数据组合,可以充分发挥各自特点,达到相互印证、互为补充的目的。根据方案研究区内主干断裂、隐伏断裂、活动断裂和断陷盆地的特点,选择有针对性的遥感图像处理方法,可以进一步突出解译目标,提高解译效果。通过对遥感解译成果、既有资料、地面调查和勘探验证成果的综合分析,将方案研究区划分为稳定区(Ⅰ)、基本稳定区(Ⅱ)、较稳定区(Ⅲ)、欠稳定区(Ⅳ)和不稳定区(Ⅴ)5个区域,为方案研究提供可靠的地质依据。结论如下:采用以遥感构造解译为先导的地质选线方法,可以快速准确获取选线所需的地质信息,为地面调查和勘探验证工作提供指导,有效提高方案研究的效率和质量。With reference to the geological route selection of Watang-Rizhao railway passing through Yishu fault zone,this paper puts forward the route selection principle for heavy haul railway in complex fault structure area and geological route selection method by means of remote sensing structure interpretation.According to the route selection requirement of reconnaissance or preliminary survey,remote sensing data of different level combination are selected to give full play to their respective characteristics and allow mutual confirmation and supplement.In order to highlight the interpretation objective and improve interpretation effect,targeted remote sensing image processing method is selected according to the characteristics of core faults,covered faults,active faults and downfaulted basin.Through comprehensive analysis of remote sensing interpretation results,existed data,ground investigation results,exploration verification results,scheme research areas are divided into five regions:stable region(Ⅰ),basic stable region(Ⅱ),relative stable region(Ⅲ),relative unstable region(Ⅳ),unstable region(Ⅴ),which provide reliable geological basis for scheme research.It is concluded that the geological route selection method with remote sensing structure interpretation as the guide can rapidly and accurately obtain the geological information required for route selection,provide guidance for ground investigation and exploration verification,and improve efficiency and quality of scheme researches.
