经实测,花地公路滑坡为“特大型”中层推移式滑坡,地灾体危害大。文章在对花地滑坡的地质地貌条件及变形特征进行深入调查的基础上,依据地质勘探资料、设计成果,分析了影响滑坡稳定性的因素,采用传递系数法对花地滑坡在不同状态下的稳定性进行了计算和评价。研究表明:自重状态及自重+地震状态下,该滑坡基本稳定;在自重和暴雨状态下,该滑坡欠稳定,该成果对后期防治工程设计至关重要。
After the test, the landslide of Huadu Highway is a “oversized” middle sliding landslide, and the damage to the disaster area is large. Based on the investigation of geologic and geomorphic conditions and deformation characteristics of Hualan landslide, the paper analyzes the factors that affect the stability of landslide according to the geological prospecting data and design results. By using the transfer coefficient method, Stability was calculated and evaluated. The research shows that the landslide is basically stable under self-weight and self-weight + earthquakes, and the landslide is not stable under heavy and heavy rain conditions. The result is very important for the design of later prevention and control engineering.
