摘　　要：为了搭建对隧道病害模拟与治理考虑更充分的隧道结构模拟综合试验平台,发明了一种管片段与现浇混凝土段组合结构,针对管片段与现浇段分别设计两种具体施工方案,结合计算工期、价格和所需机械数量,同时考虑了现场条件与需求优先级,比选确定了施工方案。结果表明:管片段采用错缝拼接施工方案搭接紧密,受力合理;现浇段采用脚手架+木模施工方案价格最优、运输方便。该隧道结构模拟综合试验平台施工方案可为其他试验平台的施工提供参考。To build a comprehensive test platform for tunnel structure simulation with more consideration for tunnel disease simulation and treatment,a composite structure of pipe segment and cast-in-place concrete segment was invented.Two specific con-struction schemes were designed for the pipe segment and cast-in-place concrete segment respectively,and the construction scheme was determined by comparing and selecting according to the calculation of time limit,price,and quantity of machinery required,as well as the site condition and demand priority.The results show that the staggered splicing construction scheme of the pipe segment is tightly bonded and has reasonable structural force.The construction scheme of scaffold+wood formwork in cast-in-place concrete seg-ment has the best price and convenient transportation.The construction scheme of the tunnel structure simulation comprehensive test platform can provide a reference for the construction of other test platforms.
