大面积深基坑开挖对邻近桥梁影响问题在现今施工中越来越频繁出现。本文结合天津市卫昆桥雨水泵站的泵站主基坑开挖工程,应用数值模拟软件ABAQUS建立有限元模型。通过数值计算,得到了基坑开挖导致的桥梁承台桩基础的水平位移和竖向位移。基于计算结果对桥梁安全进行了评估,供设计和施工参考。
大麵積深基坑開挖對鄰近橋樑影響問題在現今施工中越來越頻繁齣現。本文結閤天津市衛昆橋雨水泵站的泵站主基坑開挖工程,應用數值模擬軟件ABAQUS建立有限元模型。通過數值計算,得到瞭基坑開挖導緻的橋樑承檯樁基礎的水平位移和豎嚮位移。基于計算結果對橋樑安全進行瞭評估,供設計和施工參攷。

For recent years,the excavation of large deep foundation pit has influenced nearby bridges frequently. Based on foundation pit excavation project of Tianjin Weikun Bridge rainwater pump station,a finite element model was built by using numerical simulation software ABAQUS. The corresponding numerical calculation led to the horizontal and vertical displacement of the bridge platform pile foundation affected by foundation pit excavation. Thus the safety of the bridge was assessed and the advices for the design and construction process were proposed in accordance with the calculation results.
