摘　　要：结合锦承线铁路扩能工程东南山铁路隧道侧穿既有建筑的工程实例,基于数值分析方法对隧道施工全过程进行模拟,评价新建隧道建设过程中及隧道建成后对既有建筑物的影响程度,提出保证新建铁路建设安全、保证既有建筑安全的要求和措施。研究结果可为类似工程的设计与施工提供借鉴及参考。In combination with the engineering project of Dongnanshan railway tunnel passing through the existing buildings in Jincheng railway expansion project,the whole process of tunnel construction is simulated based on the numerical analysis method,the degree of influence on the existing buildings during and after the construction of newly-built tunnels is evaluated,and the requirements and measures to ensure the construction safety of the newly-built railways and the safety of the existing buildings are put forward.The research results can provide reference for the design and construction of similar projects.
