基于深圳彩田路新彩隧道北口段(拟建)近距离上跨厦深铁路梅林隧道两条隧道叠置的工程实例，运用有限元分析软件MIDAS-GTS 进行三维模型数值分析，研究了新建隧道拟用施工方案及加固方案的可行性，分析了新建隧道在施工及运营阶段，既有隧道的变形及内力变化规律，并对既有隧道的安全性进行了评价，结果表明：选用的施工方法在新建新彩隧道施工及运营阶段不会影响既有线路的运营安全性。

Based on two tunnel overlapping engineering example of Xincai tunnel north section on Caitian road in Shenzhen over-crossing Meilin tunnel of Xia-Shen railway, the paper applies finite element analysis software MIDAS-GTS and carries out three-dimensional numerical simula-tion, studies the feasibilities of new tunnel construction scheme and reinforcement scheme, analyzes existing tunnel deformation and its internal force alteration law at new tunnel construction and operation phases, and estimates existing tunnel security. Results show that: the selected con-struction method will not influence existing tunnel line operation safety at Xincai tunnel construction and operation phases.
