Design method of low lower tower column bridge tower without lower cross beam
The invention discloses a design method for a low lower tower column bridge tower without a lower cross beam, and relates to the technical field of bridge engineering, the method comprises the following steps: judging whether a bridge tower structure without the lower cross beam is adopted according to the bending moment of the bridge tower with the lower cross beam and the bridge tower without the lower cross beam in the transverse bridge direction; if the lower-beam-free bridge tower structure is adopted, whether the section of the set position of one tower column is completely pressed or not is judged; if the sections of the set positions of the tower columns are all pressed, the buttress and tower column integrated bridge tower is adopted, otherwise, the buttress and tower column separated bridge tower is adopted. The problem that in the prior art, when a low lower tower column bridge tower is designed, a structure that a lower cross beam is arranged to support a main tower is adopted, and a reasonable bridge tower design structure cannot be judged according to the stress condition of the tower column is solved.
本发明公开了一种无下横梁低矮下塔柱桥塔设计方法，涉及桥梁工程技术领域，该方法包括根据有下横梁与无下横梁的桥塔横桥向弯矩大小，判断是否采用无下横梁桥塔结构；若采用无下横梁桥塔结构，判断其中一塔柱设定位置截面是否全部受压；若塔柱设定位置截面全部受压，采用支墩与塔柱整体式桥塔，否则采用支墩与塔柱分离式桥塔。解决了现有技术中低矮下塔柱桥塔设计时，采用设置下横梁支撑主塔的结构，存在没有根据塔柱受力情况，判断合理的桥塔设计结构的问题。
