直升机在连续档牵放导引绳施工中的受力计算

The Calculation of Tension Towing a Helicopter in Stringing Engineering during Releasing the Leading string between Continual Span Poles

根据直升机架线施工的经验，就直升机牵放导引绳施工较为关键的直升机受力、控制档张力、张力机出口受力等计算作了介绍。该计算方法可供特大山区５００ ｋＶ架线、三峡外送工程等利用直升机施工时参考。

The overall electric transmission engineering from the “Three Gauge” project will be started up soon.It is quite possible that the helicopter will be adopted for the construction of the 500 kV transmission lines in the special mountainous area.As a reference according to our engineering experiences,this article described and introduced the key calculations of the forces applied to the helicopter and the tension control between the spans of the poles and the force on the outlet of the tension machine under the situation where the helicopter releasing the leading string.
