摘要
通过多方案数值计算并与现场实测对比的分析方式,对暗挖段施工引起上部结构不均匀变形的产生原因进行了详细深入的探讨,得到了有实用价值的结论,成功指导了现场进一步的施工工作,并最终使上部结构不均匀变形得以控制。
In this paper, the influence and reasons of the asymmetrical deformation of upper structure due to excavation of underside tunnel were studied in detail by numerical simulation and comparing with the site-test. The results are valuable for the next steps of the construction, by which the asymmetrical deformation of upper structure was controlled at last.
