摘要
尼泊尔工程地质条件复杂,工程建设面临多种地质灾害威胁。通过收集文献,初步分析了尼泊尔的地质构造、地形地貌、地层岩性、水文地质条件和不良地质现象等工程地质条件。结果表明:①尼泊尔4条近东西向断裂可将其划分为5个构造单元;②尼泊尔地形起伏大,可划分为8个不同的地貌单元;③发源于青藏高原的8条主要河流在纵向上将尼泊尔划分为六大流域;④对工程建设造成不利影响的不良地质现象主要包括地震、崩塌、滑坡和泥石流等,在工程建设初期应充分评价地震及“崩滑流”对建设场地的不利影响,重点项目建议开展专项研究。研究成果可为尼泊尔工程建设提供技术支撑。
The complex engineering geological conditions of Nepal may lead to the risk of geological disaster for project construction.The engineering geological conditions of Nepal,such as geological structure,topography,lithology,hydro-geological conditions,and adverse geological phenomena,etc.,was analyzed by collecting literature.The results showed that:①4 faults,with nearly east-west strike,can divide Nepal into 5 longitudinal geological zones distributed from north to south.②The landform of Nepal undulates terribly,and the territory of Nepal can be divided into 8 roughly parallel geomorphic regions.③8 rivers,running out of Qinghai-Xizang Plateau,can divide Nepal into 6 transverse physiographic regions.④The harmful engineering phenomena that have a negative impact on engineering construction in Nepal mainly include earthquakes,collapses,landslides and mudslide,etc.The adverse effects of earthquakes,collapses,landslides and mudslide on construction sites should be fully evaluated in the site selection stage of construction projects,and special studies were suggested for key projects.The research results could be a technical support for engineering construction in Nepal.
