摘要
本文在对岚皋县柳家坡滑坡群进行野外调研的基础上,论述和分析了该滑坡群的自然地质环境、工程地质特征及形成滑坡的主要因素。文章认为,因有构成河流阶地基座的软弱的千枚糜棱岩充当滑床和在滑床与滑体间有充分起润滑作用的水的供给,是柳家坡滑坡产生的根本原因。本章最后还对滑坡群的防护和治理措施提出了看法和意见。
Based on the data obtained through an investigation on the Liujiapo landslides at the Langao County, Shaanxi Province, this paper discusses the nature-geological environment, the hydrogeological and engineering-geological conditions, and analyses the main faotcrs which influenced the landslide formation.The paper consideres that the basic reasons of the landslide formation are. ( 1 ) the physite-mylonite has been acted as the sliding bed here, and ( 2 ) the places between the sliding bed and the sliding mass have sufficient groundwater. Lastly, the paper puts forward some rationalization proposals on the prevention and the harnessing of these landslides.
