滑坡勘查中关键问题的识别与案例应用

Identification and Case Application of Key Problems in LandslideInvestigation

山地丘陵地貌在我国分布广泛,滑坡地质灾害多发,严重制约着我国社会经济的发展。以滑坡地质灾害为研究对象,提出了在滑坡勘查中需要重点关注解决的四个关键技术问题,包括滑坡特征调查与稳定性定性评价、滑带识别与位置判定、参数取值和计算模型确定、滑坡稳定性定量分析。结合典型案例应用分析,提出了相应的解决方法,掌握了滑坡特征及目前稳定性状态,为后续滑坡防治工程设计提供充分且必要的地质基础资料,同时为滑坡地质灾害勘查提供借鉴。

The mountainous and hilly landforms are widely distributed in China,and the geological hazards of landslides are frequent,which seriously restrict the development of China’s social economy.Based on landslide geological hazards,four key technical issues are identified and mainly solved in the landslide exploration.It includes landslide characteristics investigation and stability qualitative evaluation,sliding belt identification and location determination,parameter value and calculation model determination,and landslide stability quantitative analysis.Combined with the application analysis of typical cases,the corresponding solutions are provided,and the landslide characteristics and current stability state are studied.This research could provide sufficient and necessary geological basic data for the follow-up landslide prevention and control engineering design,and also provide reference for landslide geological disaster investigation.
