重大滑坡隐患分析方法综述

A review of major potential landslide hazards analysis

滑坡是发生频繁且破坏力巨大的典型地质灾害类型,高位山体崩滑和冰雪崩滑等重大滑坡隐患已经成为新型城镇化和川藏铁路工程等重大基础设施建设重要的制约因素。本文系统归纳总结了现有滑坡隐患监测技术和分析方法的特点与局限,提出了一种数据驱动与模型驱动协同的滑坡隐患可靠分析方法,构建滑坡隐患分析知识图谱、提取高层语义特征指标、知识引导精准判别滑坡隐患。该方法系统考虑了深部-地表内外动力耦合作用的致灾机制,为小样本、高复杂度的滑坡隐患可靠分析提供了新途径。

Landslide is a typical and frequent geological disaster, which causes great loss to human beings. Major landslide hazards, such as landslides in high mountains and ice avalanches,have become important constraints to the development of urbanization and major infrastructure projects such as the Sichuan-Tibet railway. This paper systematically analyzes the characteristics and limitations of existing monitoring technology and analysis methods of potential landslide hazards, introduces a reliable method for potential landslide hazards analysis by coupling monitoring data with mechanism models, to establish the knowledge graph for potential landslide hazards analysis, to extract the high-level semantic features and to identify the potential landslide hazards precisely guided by knowledge.This method systematically considers the mechanism of landslide disaster caused by the coupling of deep and surface, and provides a new way for the reliable analysis of potential landslide hazards with small sample and high complexity.
