倒落抱杆整立杆塔施工中 ,吊点位置的确定是一项非常重要的设计内容。采用“弯曲应变能最小”准则 ,搜索最优吊点位置 ,可显著降低杆塔最大截面弯矩 ,使之满足杆塔结构强度及抗裂要求。该法适用于任意多吊点、任意荷载、任意变截面等多种情况。 Falling pole pole tower construction, the location of hanging point is a very important design content. Using the criterion of “minimum bending strain energy” and searching the optimal lifting point position, the bending moment of the maximum section of the tower can be significantly reduced so as to meet the structural strength and crack resistance requirements of the tower. The law applies to any number of hanging points, any load, any variable cross-section and other circumstances.
