摘要
以北京地铁十号线国贸站工程为例,对复合锚杆桩在隧道下穿桥桩加固土体中的应用进行了介绍,分别阐述了桥桩保护方案,设计参数及施工方法,实践结果表明复合锚杆桩提高了桩周土体整体性且工艺简单,值得推广。
Taking Guomao station of No. 10 subway in Beijing, the paper introduces the application of the composite anchor pile in bridge piles＇ intensification soil body undercrossing subway tunnel, illustrates the protection scheme for bridges, the design parameter and the construction methods, and proves the composite anchor pile can improve the wholeness of the pile intensification of the soil body and can be extended further.
