The main risk sources in the construction process are analyzed, including foundation pit and shield construction adjacent to the existing Shanghai – Hangzhou high - speed railway, side crossing and under crossing existing rail transit lines, high - voltage line towers, municipal pipe networks, municipal roads, bridges and tunnels, and under crossing Pudong airport taxiway and satellite hall. The innovative technical means to deal with various potential risks are sorted out, including the intelligent construction technology of ultra long - distance underground railway with high - risk and thick confined aquifer, the risk intelligent control technology of ultra long - distance municipal underground railway in complex environment, the ultra long - distance disaster prevention, rescue and evacuation technology in urban core area under the condition of interconnection with national railway, the construction technology of mechanical connection channel of municipal high - speed railway key technologies of water and soil risk control and high - precision measurement perception and early warning of municipal high - speed railway, platform architecture of Municipal Railway Intelligent transportation management system, etc. Keywords: m unic ip al h ig h-s p eed r a ilw ay; tu nnel e ng in eerin g ; r is k s o urc e a naly sis ; in nova tiv e c ounte rm easu re s 纵 观国内其他地区地下高速铁路建设项目，京广高铁 石 家庄地下线 [1 ]周 边建筑稠密、下穿城市主干道，广深港 高 铁地下线 [2 ]穿 越有高压涌水风险的软弱地层环境，济青 高 铁青岛红岛线 [3 ]穿 越主要城区。与之相比，上海市域铁 路
