输电线路微型桩基础应用分析

Transmission Line Analysis of the Application of Micro-pile Foundation

针对输电线路杆塔在软土地基中的基础,结合国家电网公司"两型三新"试点线路建设的安排,拟在500 kV庐桐-安庆变电站线路中河网、泥沼地段地基承载力较低的塔位,采用微型桩基础代替一般的大直径钻孔灌注桩,文中通过微型桩基础和一般大直径灌注桩基础、钢筋砼板式基础的技术经济比较,分析出其社会经济效益并提出需近一步研究的问题和建议。

In view of transmission line tower foundation in soft soil,combined with State Grid Corporation of the＂two-type three-new＂ arrangements for the construction of the pilot line,to be in the 500 kV Lu Tong-Anqing river substation fines, low bearing capacity of foundation mire Lot the tower,and the use of micro-pile foundation instead of a general large-diameter bored piles,through the micro-pile foundation and the general large-diameter pile foundation,reinforced concrete slab foundation for technical and economic comparison ,the analysis of its recommendations. benefits and to be further research and
