Abstract

Cutandcover method, long pipe roof and protection arch subsoil reinforcement technology are used in shallowburied section of Shilin tunnel located in soft subsoil, so as to reduce the construction difficulty and risk and to realize rapid and safe construction. The cutandcover method is simple and with less cost. The paper can provide references for similar projects in the future.

Key words： tunnel; soft subsoil; shallowburied; cutandcover method
