桥梁建设过程中,由于受地形、地质、施工条件等因素的影响,在外力作用下经常造成桥梁桩基及桥墩偏斜的事故,在出现较大偏差时必须进行及时纠偏,以避免不必要的经济损失。文章针对软基上由于堆载产生的桥梁桩基位移,导致桥梁上部结构产生14cm错位的实例,通过理论分析,确定桩基位移的原因并确定纠偏方法,取得成功。本实例的介绍以期对省内外同类情况提供一定的参考价值。
Due to the influence of topography, geology, construction conditions and other factors during the process of bridge construction, under the action of external forces, accidents of skewing of bridge pile foundation and bridge piers are often caused. In the event of a large deviation, timely corrections must be made to avoid unnecessary Economic losses. In this paper, a case of 14cm dislocation in the superstructure of the bridge is caused by the pile foundation displacement caused by pile loading. By theoretical analysis, the cause of pile foundation displacement is determined and the correction method is determined, which is successful. The introduction of this example is intended to provide some reference value for the similar situations inside and outside the province.
