摘要
Lining structure in yuanliangshan tunnel of yuhuai railway loads high water pressure, so bedding and inverted arch concrete quality have great importance to working safety. We have applied ground probing radar (GPR) to detect bedding concrete quality of tunnel, and then studied non-destructive detecting means of bedding concrete quality in section of karst caves inside the tunnel and application technologies of GPR, in succession analyzed characteristics of GPR pictures about empty slag at the bottom of bedding, cracking of surrounding rock, and disfigurement of lining structure inside the tunnel, finally brought forward some problems existing of GPR in the course of non-destructive detecting in tunnel construction.
