摘　　要：针对北京L14京顺路站深基坑近邻望京沟桥桥桩的风险工程,研究分析基坑施工对望京沟桥的影响,提出采用复合锚杆桩的隔离保护措施。通过有限元计算分析近接施工中基坑开挖与桥桩的相互影响,结合现场监测,表明采用复合锚杆桩隔离望京沟桥桩基的措施是安全可靠的,可为今后类似施工提供设计参考。Based on the risk engineering that the pier of Wangjinggou Bridge being adjacent to the deep foundation of Jingshun Rd. station of Beijing Metro L14, the influence of foundation pit construction to Wangjinggou Bridge is analyzed and researched, and the isolation protection measures of composite anchor pile are proposed in this paper. By analyzing the interaction between foundation pit excavation and pier during the adjacent construction based on finite element calculation and considering the situ-monitoring, the measure to use composite anchor pile in isolating the pier foundation of Wangjinggou Bridge is proved to be safe and reliable, which can provide references for similar projects in the future.
