四川省会理县昆鹏铜业滑坡稳定性研究

Study on Landslide Stability of Kunpeng Copper Industry in Huili County,Sichuan Province

【目的】分析昆鹏铜业滑坡在不同工况下的稳定性情况,并针对性地提出治理建议。【方法】采用Geostudio软件模拟滑坡在受自然工况、暴雨工况、地震工况影响下的稳定性变化。【结果】昆鹏铜业滑坡在自然工况下处于基本稳定状态,在暴雨影响下滑坡稳定性从基本稳定状态变为不稳定状态,在7级及以上地震的影响下滑坡也会从基本稳定状态变为不稳定状态造成滑坡失稳。【结论】目前滑坡处于蠕滑阶段,必须对滑坡进行治理,建议完善滑坡区域的排水措施,对滑坡进行支挡和裂缝填塞处理。

[Purposes]This paper analyzes the stability of the Kunpeng copper landslide under different working conditions,and puts forward targeted treatment suggestions.[Methods]Geostudio software is used to simulate the stability changes of landslides under the influence of natural working conditions,heavy rainfall conditions and seismic conditions.[Findings]The Kunpeng copper landslide is in a basically stable state under natural working conditions,and the stability of the landslide will change from a basic stable state to an unstable state under the influence of heavy rainfall,and the landslide will also change from a basic stable state to an unstable state under the influence of earthquakes of magnitude 7 and above,resulting in landslide instability.[Conclusions]At present,the landslide is in the creep-slip stage,and the landslide must be treated,and it is recommended to improve the drainage measures of the landslide area,and carry out support and crack filling treatment for the landslide.
