福州地铁洗马桥桩基托换方案研究

摘要

结合福州地铁洗马桥工程实际情况,探讨了该桥桩基托换方案,通过对比分析不同方案的成本、技术难度,确定了适合本工程的托换及除桩技术方案,并提出相应的辅助施工技术,为顺利施工提供了指导,并达到减小社会影响、缩短施工周期和降低工程造价的目的。%Combining with the factual circumstance of the pile foundation underpinning of Xima Bridge in Fuzhou subway,the paper compares and analyzes the costs and technical difficulties of various schemes,identifies the suitable underpinning of the project and the pile removing technical scheme,and points out the respective auxiliary construction technique,and provides certain direction for the smooth construction,so as to reduce the social influence,shorten the construction period and lower the engineering costs.
