Abstract: She Hai metro running of Shenzhen metro line 2 is a double line shallow buried tunnel which is excavated by
m ine method Stratum s of this section is not only varied but also water rich, and left line need to cross a building called
Taizi hotel on the ground Construction techniques including sleeve valve p ipe, deep hole grouting, p ipe shed advance sup
port and blasting control measures are introduced in detail to illustrate how to ensure the security of excavation Reinforce
ment effects and ground settlement control are verified by numerical simulation
Key words: shallow buried tunnel; building; construction techni
