结合工程实际，对双吊车四个吊点整体起吊500kV线路铁塔的施工方案进行了详细的阐述，通过铁塔重心位置计算，利用简化模型，力矩平衡理论，逐点比较等方法选择出最优吊点位置，按照安全规程要求合理选择工器具，并对施工操作要点进行了叙述。
결합공정실제，대쌍조차사개조점정체기조500kV선로철탑적시공방안진행료상세적천술，통과철탑중심위치계산，이용간화모형，력구평형이론，축점비교등방법선택출최우조점위치，안조안전규정요구합리선택공기구，병대시공조작요점진행료서술。
In accordance to engineering practice, process schemes for single-piece erection in 500kv transmis- sion line are discussed in details. In the process, gravity center of the steel tower is computed, and optimum hoist-point is selected in applying simplified model and theory of balance movement and point-to-point compar- ison method, and tools and appliances are chosen according to security requirement and operation essentials are elaborated here.
