| Abstract: | The working principle,the layout method of surveying line and parameters characteristics of GPR are introduced in the paper,combined with the theory of electromagnetic wave reflection,the interpretation method of GPR are discussed;then according to the application of GPR in geological forecast for expressway tunnel,the imaging characteristics of some typitical geology bodys such as intact rock mass,fault fracture zone,water enriched zone,fissure dense zone and karst development etc.are analyzed and demonstrated;the examples prove that the application of GPR in advanced geological forecast is feasible for field construction. |
| Keywords: | GPR advanced forecast tunnel data interpretation engineering geology |
