摘要
1000kV特高压线路输送容量大,重要性远高于其它高压线路,必须保证采动影响区的线路安全可靠。本文就某1000kV特高压交流线路工程经过的长壁陷落和巷道式二种典型采空区的特征、性质、输电线路杆塔地基稳定性进行研究,并提出这二种采空区杆塔地基稳定性的评价方法。工程应用实例表明,研究成果具有实用性,可解决实际工程问题。
The transmission capacity of 1000kV unltra high-voltage is large,which is far more important than the other transimission line.So the mining influencing area should be safe and reliable.The characteristic,properties and stability of tower foundation of the typical longwall collapse goaf and tunnel goaf in some AC transimission line of 1000kV ultra high-voltage were studied.And the evaluating methods to the stability of tower foundation in the two types of goaf was put forward in this paper.The engineering application case indicates that the study result is of practicability,which can deal with the practical engineering problems.
