| 摘 要： | 在地铁设计与施工中,经常遇到地铁区间、车站需穿越城市既有桥桩和房屋基础的情况,在改线和撤迁无果时就需要对既有桥桩或房屋基础进行加固或托换处理。此时,如何保障既有桥桩或房屋的安全与正常使用是整个托换的根本。文章结合工程实际,提出了主动与被动相结合的二次托换技术。

| Abstract: | Metro tunnels or stations are often designed and constructed across bridge piers and house foundations within cities.In this case,it is necessary to reinforce or change the existing foundation works when metro line change or relocation fail.How to protect the existing bridge piles or housing security and ensure normal use of the whole underpinning is of great importance.The paper draws on engineering practice to propose a combination of active and passive second underpinning technologies. |
