摘　　要：由于受地形限制,牵张场地选择困难,经现场勘查塔位地形环境恶劣、牵张场布置存在较多的转向,且张力机出线至塔位需要跨越两处山脊。N13张力场场地距N13距离较远(约2 km左右),同时张力场场地在当地防火救援备用直升机停机坪附近,给施工带来极大困难且施工安全风险高,故需在N13-张力场之间利用两套座地滑车过渡处理,同时在N13塔腿通过7个转向滑车至张力场。Due to the limitation of terrain,it is difficult to select the stretch site.After on-site investigation,the topography of the tower site is harsh,and there are many turns in the layout of the stretch field,and the tension machine needs to cross two ridges to reach the tower position.The N13 tension field site is far away from N13(about 2 km),and the tension field site is near the local fire rescue helipad,which brings great difficulties to the construction and high construction safety risks.Two sets of ground pulleys are used for transition processing,and at the same time,the N13 tower leg passes through seven steering pulleys to the tension field.

关 键 词：大高差 座地滑车 张力放线
