Abstract

This paper describes a recent landslide event, which occurred at Liucheng village in Tianquan County, Sichuan Province, China, on July 15, 2018. The Laochang landslide described in this research is an outstanding and valuable reference for understanding the characteristics of such kind of landslides that are geologically similar to the landslide. The deformation characteristics of the landslide are investigated based on field investigations, drilled boreholes, and exploratory trenches. The 225 residents of 64 households living on the flat platform were threatened by the landslide. Therefore, to guarantee the safety of human life and property becomes the primary emergency task. The anti-sliding piles were taken to stabilize the landslide and mitigate impacts caused by the landslide. Based on the analysis of the monitoring data, the effectiveness of anti-sliding piles is evaluated. The results indicate that the anti-sliding piles are effective in increasing the stability of the landslide, and this work can provide a reference for similar slope engineering projects.

摘要

本文描述了 2018 年 7 月 15 日发生在中国四川省天全县柳城村的一次近期滑坡事件。本文所描述的老昌滑坡为研究此类与滑坡地质相似的滑坡特征提供了一个极好且有价值的参考。通过现场调查、钻孔和勘探槽对滑坡的变形特征进行了研究。居住在平台上的 64 户 225 名居民受到了滑坡的威胁。因此，保证人类生命和财产的安全成为首要的应急任务。采用抗滑桩来稳定滑坡，减轻滑坡造成的影响。基于监测数据的分析，对抗滑桩的效果进行了评估。结果表明，抗滑桩在增加滑坡稳定性方面是有效的，这项工作可为类似的边坡工程项目提供参考。
