摘要
随着我国西电东送等输电工程的实施,越来越多的输电线路杆塔需要建立在黄土边坡上。杆塔位置的不同,会对边坡稳定性带来不同的影响。本文结合西宁市黄土地区工程实例,从极限平衡分析和有限元分析两方面阐述了杆塔合理位置的计算过程。同时为了考察边坡形态对杆塔合理位置的影响,通过计算不同坡高和坡度组合下黄土边坡的安全系数,得到杆塔合理位置与坡度、坡高之间的变化规律。
With the implementation of China＇ s West to East Power Transmission Project, a growing number of transmission line towers will be built on the loess slope. The stability of the slope will change with the difference of the tower location. The tower reasonable location calculation process is expounded combined with the project in the loess area of Xining City on the base of limit equilibrium analysis and finite element analysis. By calculating the safety factor of the slope with different height and slope, the variation among the reasonable location, the slope and height can be obtained.
