摘要
文章采用数值模拟的方法,对黄土沟谷地区格构式高墩在不同荷载条件下的墩顶偏位展开研究.结果表明,墩顶偏位随着荷载作用的增大而增大,其中,横桥向风荷载、施工不平衡荷载及最不利荷载组合作用对墩顶偏位的影响显著,在施工过程中出现不平衡荷载时,应重点关注挂篮不平衡荷载及施工机具堆积的影响.
Abstract
The numerical simulation method is used to study the top deviation of the lattice high pier under different load conditions in the loess gully area.The results show that the pier top deviation increases with the increase of load.Among them,the combination of transverse wind load,construction unbalanced load and the most unfavorable load has significant influence on the pier top deviation.When unbalanced load occurs in the construction process,special attention should be paid to the influence of unbalanced load of hanging basket and accumulation of construction machinery.
