地铁区间隧道侧穿铁路桥梁扩大基础设计浅析

Brief Analysis on Design for Foundation Expansion of Bridge Passing Railway Alongside of Interzone Tunnel in Metro

某城市地铁暗挖区间隧道侧穿铁路桥梁扩大基础,通过数值模拟计算,分析区间隧道与桥梁基础之间的相互影响,探讨隧道支护结构及桥梁基础的安全性;结合数值计算及工程类比,简要讨论了侧穿段隧道结构设计方案、技术措施及施工监控量测设计。

As for foundation expansion of bridge passing railway alongside of interzone tunnel of underground excavation of a city, the mutual influence between interzone tunnel and bridge foundation is analyzed through numerical simulation calculation, and the safety of tunnel supporting structure and bridge foundation is discussed. In combination with numerical calculation and engineering analogy, the design scheme, technological measures and construction monitoring measurement design for the structure of tunnel passin~ alongside are discussed briefly.
