摘要(Abstract):
目前宁波地区110 kV架空输电线路主要采用板式基础,存在开挖面积大、费用高等问题。通过对板式基础、掏挖式基础和岩石嵌固式基础的技术、经济指标的比较分析,指出掏挖式基础和岩石嵌固式基础的技术经济指标更优,在不同的施工要求、施工环境等条件下,因地制宜地使用掏挖式基础和岩石嵌固式基础可减少工程建设对环境的影响,节约工程投资。
Currently Ningbo 110 kV overhead transmission line application is based primarily on plate base plate foundation excavation area,high cost.Through the base plate,digging inlay type foundation and rock solid formula-based technology,economic and other indicators of comparative analysis,a clear foundation and digging style embedded rock solid foundation of technical and economic indicators formula better future can be in different construction requirements,construction and environmental conditions using local conditions and rock digging type foundation embedment type foundation,to reduce the environmental impact of construction projects,saving project investment.
