北京山区公路边坡地质灾害隐患监测预警技术研究
|
摘要
北京山区的地质构造复杂,岩层风化和破碎严重,人类工程活动频繁,故其地质环境比较脆弱,地质灾害较为发育,特别是山区公路沿线,存在着大量不稳定的人工边坡,在降雨、振动等自然和人类活动因素影响下,很容易发生崩塌、滑坡、落石等地质灾害,故很有必要对其开展专业监测和预警工作。本文主要依据监测对象的不同,对边坡变形和破坏的监测及预警技术进行了系统地总结和梳理;在认真调查和分析北京山区公路边坡变形和破坏模式的基础上,就如何有效开展边坡地质灾害隐患的监测和预警进行了初步研究和探讨,并提出了合理建议。这对今后开展相关工作具有重要的参考意义;对预防和减少山区公路边坡地质灾害损失将起到一定的作用。
In the mountainous area of Beijing, the geological structure is complicated, the weathering and breakage of rock formations are serious, and human engineering activities are very frequent; therefore, its geological environment is more fragile, and the geological disasters are relatively developed, especially along the mountainous roads. There are a lot of the unstable artificial slopes, which is easy to result in the geological disasters such as collapse, landslide and rockfall under the influence of the natural and human activities of rainfall and vibration. It is necessary to carry out the professional monitoring and early warning. In accordance with the different monitoring objects, this paper systematically summarizes the monitoring and warning techniques of the slope deformation and destruction. Based on the careful investigating and analyzing the deformation and failure modes of the slope along the roads in Beijing mountainous area, this article has conducted preliminary research and discussion on how to effectively carry out the monitoring and early warning of the potential slope geological disasters, and put forward some reasonable suggestions. It is important for the future work,and will play a role in preventing and reducing the damage of the slope geological disasters along the mountainous roads.
