中国是世界上地质灾害最严重的国家之一,其中滑坡常年位于各类地质灾害首位,因此对滑坡灾害进行深层次的研究至关重要.边坡工程常常会受到人类工程活动与自然地质作用叠加效应的影响,从而增加了对边坡变形失稳机理的科学认知难度.为精准掌握边坡状态信息与变形失稳过程,可通过建立全维度的监测体系以实现边坡状态信息的动态解译与表征,据此获得更加精准、可靠、直观的边坡稳定性评价依据.文章围绕边坡破坏模式及典型边坡监测技术,在厘清边坡变形演化过程的基础上,对边坡"天—空—地—体"一体化监测技术体系进行了全面分析;概述性总结了基于DFOS的边坡监测技术,重点阐述了基于DFOS的边坡多源多场监测研究思路与实施路径;系统性梳理了基于典型监测技术与DFOS技术的边坡物理模型试验研究过程与结果,以期为开展边坡加固方案设计与防灾减灾控灾提供重要的参考依据.
Research of Full Dimension Monitoring Technology and Model Test of Slopes
China is one of the countries with the most severe geological disasters,among which landslides are the most severe.Therefore,it is crucial to study landslide disasters deeply.Slope engineering is often affected by the superposition effect of human engineering activities and natural geological processes,which induce difficulty to scientific understanding of the slope deformation and instability mechanisms.To accurately grasp the slope state information,as well as the process of deformation and instability,a full-dimensional monitoring system is established to achieve dynamic interpretation and characterization of slope state information,thereby obtaining a more accurate,reliable,and intuitive basis for slope stability evaluation.In this paper,we comprehensively analyzes the'air-space-ground-interior'integrated monitoring technology system of slopes from the perspectives of slope failure modes,typical slope monitoring technologies,and clarification of slope deformation evolution processes;Also,this study provides an overview and summary of the slope monitoring technology based on distributed fiber optic sensing(DFOS),with a focus on the research ideas and implementation paths of DFOS-based slope monitoring with multiple sources and fields.Further more,this study systematically reviews the process and results of physical model experiments of slopes based on typical monitoring technologies and DFOS technology,aiming to provide important reference for the design of slope reinforcement schemes and disaster prevention,mitigation and control.
