贤令山滑坡为粤北山区典型的土质堆积层滑坡,总结该滑坡的发育特征并分析评价其稳定性,对于粤北山区同类滑坡具有借鉴意义[9]。本文从滑坡空间形态、滑坡物质组成及结构特征、滑坡变形特征、滑坡成因机制分析等多个方面揭示了贤令山滑坡的基本特征,采用剩余推力传递法计算滑坡稳定系数,计算结果表明自重条件下滑坡处于稳定状态;自重和暴雨条件下滑坡处于欠稳定状态。
賢令山滑坡為粵北山區典型的土質堆積層滑坡,總結該滑坡的髮育特徵併分析評價其穩定性,對于粵北山區同類滑坡具有藉鑒意義[9]。本文從滑坡空間形態、滑坡物質組成及結構特徵、滑坡變形特徵、滑坡成因機製分析等多箇方麵揭示瞭賢令山滑坡的基本特徵,採用剩餘推力傳遞法計算滑坡穩定繫數,計算結果錶明自重條件下滑坡處于穩定狀態;自重和暴雨條件下滑坡處于欠穩定狀態。

Xianling mountain landslide for the typical soil accumulation landslide of the mountains of northern Guangdong,summarize the development of a landslide features and analysis to evaluate the stability,reference similar landslide for the mountains of northern Guangdong. Based on a large number of exploration data from the spatial form of landslide,landslide material composition and structural characteristics of landslide deformation characteristics of the landslide hydrogeology,Landslide analysis has revealed the basic characteristics of the Yin--order landslide,on this basis,the use of The remaining thrust transfer method to calculate the landslide stability factor calculations show that the weight conditions under the landslide in a stable state,landslide in owed stable state under the weight and heavy rain conditions.
