摘要:
我国西南及邻近的复杂艰险山区，具有地形高差显著、地质复杂多变、构造活动强烈等环境特征，地质灾害广泛发育，地质灾害问题十分突出。开展地质灾害识别是减灾选线的前提，面向基于风险管理、全寿命周期、系统工程的铁路减灾选线，必须重视地质灾害广域高效识别理论与技术的研究。本文研究表明：地质灾害识别可划分为区域宏观识别、沿线系统识别、区段详细识别"三阶段"，综合应用天域卫星平台、空域航空平台、地域地面平台"三维度"识别技术，分阶段开展灾害特征、演化机理、灾害风险"三层次"识别，由此创建"三阶段、三维度、三层次"地质灾害广域高效识别模式与方法，形成复杂艰险山区地质灾害广域高效识别技术体系，能够显著提高山区铁路地质灾害识别的效率、质量和水平，在山区铁路建设中具有广阔的应用前景。
Abstract:
The complex and dangerous mountainous areas in Southwest China and its adjacent areas have the environmental characteristics of significant topographic height difference, complex and changeable geology and strong tectonic activity, where the geological disasters are widely developed and the problem of geological disasters is very prominent. The geological disaster identification is the premise of disaster reduction and route selection. For the railway disaster-reduction route selection based on risk management, life cycle and system engineering, it is necessary to pay attention to the study on the theory and technology for wide-area and high-efficiency identification of geological disasters. The study results show that geological disaster identification can be divided into three stages, including regional macro identification, system identification along the line and detailed identification of the section, by using the "three-dimension" identification technology of space satellite platform, airspace aviation platform and regional ground platform, the "three-level" identification of disaster characteristics, evolution mechanism and disaster risk is carried out in stages, thus the wide-area and high-efficiency "three-stage, three-dimension and three-level" identification mode and method for geological disasters is established to form a wide area high-efficiency identification technology system of geological hazards in complex and difficult mountainous areas, significantly improve the efficiency, quality and level of geological disasters identification in the railway in mountainous areas, which has broad application prospects in the construction of railway in mountainous areas.
