摘　　要：结合国内在建及运营水下铁路隧道工程,从工程地质、投资、建设条件、运营条件等方面分析了影响水下铁路隧道分合修的因素。结果表明:工程建设条件和实施难度是分合修方案选择的控制因素;在建设条件均可行时,工程投资为影响分合修方案的重要因素之一;接线设站形式、横通道施工安全、防灾疏散救援、运营安全和养护维修等为影响分合修方案的次要因素。Combined with domestic construction and operation of underwater railway tunnel projects,considering the characteristics of engineering geology,investment,construction conditions and operation conditions,this paper analyzes the influence factors of single double-track tube and twin single-track tubes of underwater shield tunnel in railway.Research has shown that:construction conditions and implementation difficulty are the most important factors,engineering investment is one of the secondary important factors when construction condition is feasible;the railway station forms,the construction safety of horizontal passage,the principles of disaster prevention and evacuation,operation safety and operation and maintenance are the third important factors which influence tunnel scheme.
