摘要/Abstract

摘要： 结合深圳地铁5号线百—布区间桩基托换实例，介绍桩基托换技术的施工流程及相应工艺。通过监控量测最终证明了预应力主次梁系主动托换形式以及自锁式抗震节点处理的重要意义，对后续类似工程提供一定的参考价值。

Abstract: The pile foundation underpinning procedure and technology are presented, with the file foundation underpinning construction of Baigelong stationBuxin station section on Line 5 of Shenzhen Metro as an example. The importance of the underpinning mode of prestressed concrete beamandgrider and treatment of selflocking antishock node is proved by means of monitoring. The paper can provide reference for similar projects in the future.

Key words: Shenzhen Metro, underneath crossing, building, pile foundation underpinning
