随着风力发电机发电容量的日益增大,风力发电塔结构越来越重要.由于预应力混凝土塔架相对于钢塔架具有造价低、刚度大、稳定性好、耐腐蚀、节约钢材和现场施工方便、维修费用低等优点,使得预应力混凝土结构有更好的发展前景.本文通过考虑风荷载引起的应变速率对混凝土强度提高的影响,对风力发电整体式预应力混凝土塔架进行了结构分析和设计计算,得到预应力混凝土塔架底截面的预应力筋和非预应力钢筋的配筋设计.%As generating capacity of the wind-turbine increases day by day, the wind-turbine tower's structural analysis is more and more important. The prestressed reinforced concrete wind turbine tower would have a wide prospect because of its advantages such as low cost, large stiffness, better stability, better durability, saving steels and convenient manufacture in-site, low maintaining cost. Considering the effect of the strain rate on the strength of concrete , the structural analysis and design are carried out for the prestressed reinforced concrete wind turbine tower, and the quantity and arrangements of prestressed and non-prestressed steel bars are obtained for the bottom across section of the prestressed reinforced concrete wind turbine tower.
