摘要:
以串列、矩形、菱形、L形和斜L形5种四塔组合方案为例,基于刚体测压风洞试验获得了不同四塔布置形式下冷却塔群表面风荷载分布模式.建立了塔筒-支柱-环基的一体化有限元模型,探讨了不同来流风向角下四塔布置形式和相对位置对风致响应的影响规律.验算了塔筒局部稳定性和整体屈曲稳定性,对比分析了四塔塔群的极限承载能力.结果表明:四塔布置形式对冷却塔位移响应、筒体环向弯矩和支柱扭矩影响较大,基于响应的四塔布置形式优选方案中串列布置形式性能最优,菱形、斜L形、矩形和L形次之;串列和斜L形布置形式在稳定性能方面较其余四塔布置形式更优,而L形、菱形和矩形布置形式的临界风速分别为串列布置形式的65%,70%和60%.
Abstract:
Taking the single row, rectangular, rhombic, L-shaped, and oblique L-shaped four-tower combinations as examples, the wind load distribution models were obtained based on wind tunnel tests for rigid bodies with different four-tower combinations. A finite element model for a tower shell-herringbone column-circular foundation-pile integration tower system was established. The influence rules of different four-tower combinations and relative positions on the wind-induced response were discussed. The local stability and the overall buckling stability of the cooling tower were checked, and the ultimate load-carrying capacity of the four-tower combinations was compared and analyzed. The results show that the form of the four-tower combination has great influence on the displacement, the circumferential moment of the tower shell and the torque of the column. From the perspective of the wind-induced responses, arranging the four towers in a row is the best choice for the form selection of the four-tower combination, successively followed by the combinations in oblique L-shape, rectangular, L-shape and rhombic. The row and the oblique L-shaped combinations exhibit obvious advantages in stability performance compared with other combinations. The critical wind speeds of the L-shape, rhombic and rectangular layout schemes are 65%, 70% and 60% of the critical wind speed of the row layout scheme, respectively.
