| 中文摘要: |
| 为消除津围公路K4段滑坡次生的地质灾害隐患,保障公路通行车辆和人员的安全,在充分收集并分析已有相关地形、地质资料的基础上,对津围公路北二线(K4+350-K4+460段)滑坡开展现场踏勘、调查,查明滑坡分布、规模及发生发育过程,分析诱发滑坡的主要因素,探讨该滑坡地质灾害的发育机理。研究结果表明:导致该地区滑坡产生的自然因素包括地形、地质条件和大气降水三方面。研究区岩石破碎、构造发育,顺层面产生泥化夹层诱发滑动产生滑坡,为中型、浅层、破碎岩体、牵引式滑坡。研究成果可为下一步深入治理提供相关地质资料和设计参数。 |

| To eliminate the hidden danger of geological hazard caused by landslide at K4 section of Jinwei highway, ensure the safety of highway vehicles, on basis of analyzing the existing topography and geological data, the site exploration and investigation are carried out at K4+350--K4+460 section in the north second line of Jinwei highway. Find out the distribution, scale and development process of the landslide, analyze the main factors which induced landslide, and discuss the development mechanism of the landslide geological disasters. The results show that the natural factors leading to landslide in this area including topography, geological conditions and meteoric precipitation. The rocks fragmentized and the structure developmented in this study area. The slide induced by mud-intercalation along the bedding and caused landslide. It is a medium, shallow, fragmentized rocks and traction landslide. The research results can provide relevant geological data and design parameters for further treatment. |
