摘　　要：深圳地铁2号线蛇海区间采用盾构法＋矿山法施工，但由于受地层及周边环境的限制，隧道接合部难以按原设计进行施工。经过研究比对，实际施工时采用了一种新的施工工艺，问题得以顺利解决，可供类似工程参考。Shield-driven method is adopted in the construction of She-Hai metro running of Shenzhen metro line 2 combined with mining method. Due to geological condition and restriction of surrounding environment, it＇s of great difficulty to follow the construction procedures of joint section between shield-driven tunnel and mined tunnel based on original design. Thus, a new alternative construction technique is adopted to solve the problem through careful study and comparison of various schedules, which could provide reference for similar projects in the future.
