| Abstract: | During the construction of the tunnel,the means used in tunneling is different from that of geological condition.The construction quality and safety misadventure in terms of cave-in,landslide and roof fall etc.take place frequently at tunnel opening under construction.This paper introduces the construction technique for opening section of shallow buried water conveyance tunnel under several typical geologic conditions,which can provide the reference for other similar projects. |
