为了揭示山区平缓地貌巨厚层堆积体滑坡的破坏机制,以旺隆互通大滑坡例,通过资料搜集整理和分析、现场工程地质调查与勘探和室内外的物理力学试验,分析降雨作用下碎石土滑坡的破坏过程,揭示了降雨作用下中深层碎石土滑坡破坏的主要机制。结果表明,一定强度的持续降雨或强降雨是中深层碎石土滑坡发生失稳的主要诱发因素;采用不平衡推力法与动态监测,分析该类型滑坡在降雨作用下所处的实际状态及滑坡的滑动过程。通过对滑坡稳定性进行准确评价,针对该滑坡的提出综合治理措施。
In order to reveal the damage mechanism of landslides with huge thick layers in the gentle landform of mountainous area, a case study of Wanglong interoperability landslides was conducted. Through data collection and analysis, field engineering geological survey and exploration, and physical and mechanical tests both indoors and outdoors, The process of landslide destruction reveals the main mechanism of the landslide damage of medium and deep gravel lands under rainfall. The results show that a certain intensity of continuous rainfall or heavy rainfall is the main inducing factor of instability of landslides in medium and deep gravel landslides. By using unbalanced thrust method and dynamic monitoring, the actual state and landslide of the landslides under rainfall are analyzed The sliding process. Through the accurate evaluation of landslide stability, the comprehensive control measures for the landslide are put forward.
