-----摘要:-------------------------------------------------------------------------------------------

以北京地铁14号线区间隧道穿越丰北桥为例,在采用FLAC3D软件进行数值模拟计算的基础上,结合对桥梁沉降观测数据的分析,对复合锚杆桩加固丰北桥桩基的方案进行优化。实际施工后沉降观测数据表明,优化后的加固方案较好地控制桥梁桩基的沉降,满足桥梁基础沉降的控制技术指标,为后续类似工程提供参考。



-----英文摘要:---------------------------------------------------------------------------------------

The reinforcement technology for the bridge foundations using the composite bolt piles was applied in the construction of metro tunnels adjacent to the existing bridge piles foundation in recent years. In this paper, taking the metro tunnel of line 14 in Beijing traversing under Fengbei Bridge as an example, the finite analysis model for the traversing engineering was developed based on the FLAC3D software. Though the monitoring and analysis on the settlement data of the bridge piles foundation, the reinforcing strategies on the bridge piles foundation of Fengbei bridge using the strengthening technique of composite bolt piles were optimized. It was shown by the actual settlement data recorded in-situ that the optimized reinforcing strategies control the settlement of the bridge piles foundation effectively, which was satisfying the controlled technical index of the settlement of the bridge piles foundation. The reinforcing strategies could be used for reference by the similar engineering projects.
