轨道工程盾构施工遇桩基础进行托换设计分析

Design and analysis of underpinning of pile foundation in shield construction of track engineering

轨道盾构施工经常遇到沿线原有桩基础侵入隧道而需对其进行托换,介绍了通过优化原桩基托换方案,结合可行的计算分析方法,使得工程风险变小,施工更为便捷,为解决轨道施工中常遇到的类似问题提供了很好的借鉴,具有很好的推广应用价值。

The existing pile foundation along the line often intrudes into the tunnel and needs to be underpinned in the construction of the track shield,introduces the optimization of the original pile foundation underpinning scheme,combined with the feasible calculation and analysis method,which makes the project risk smaller and the construction more convenient.It provides a good reference for solving the similar problems often encountered in the track construction and has a good promotion and application value.
