宁夏山区公路的地质灾害及工程对策
|
摘要
在充分运用现有的地质、钻探、试验测试常规调查方法的基础上,采用地理信息系统(GIS)、全球定位系统(GPS)、遥感(RS)及计算机信息处理技术等高科技方法和手段,查明宁夏山区公路地质灾害与环境地质问题的类型、发育特征、分布规律、成因和危害,总结规律,进行科学分类,即从自然原因产生的地震、滑坡、崩塌、泥石流、特殊性土灾害和人为原因所产生的破坏边坡稳定、破坏植被、水土流失、侵蚀等两方面进行分析,提出了防治山区公路地质灾害的工程对策.
Through fully utilizing previous geologic,drilling,and testing met hods,adopted geographic information system (GIS),global position system (GPS) ,remote sensing (RS),high-tech and methods of computer information technique ,fully gathering and using available materials,strengthening comprehensive ana lytical ability,this paper ascertained the categories,characteristics,distrib ution pattern,cause of formation and harmfulness of geologic disasters and envi ronment geology of mountainous highway. Then,two types of geologic disasters of mountainous highway were suggested:①caused by nature,such as earthquakes,la ndslide collapse,debris flow,and special soil disaster;②caused by human bein g's activities,they are destructions of marginal slope,vegetation destroy,los s of water and erosion of soil etc. According to the above geologic disasters,e ngineering countermeasure was advanced in the paper to prevent and cure geologic disasters of mountainous highway.
