| Abstract: | Karst is developed in west anchor hole of Balinghe Bridge.In order to ensure excavation quality and safety,the geological conditions of surrounding rock in front of tunnel heading is detected by geological prediction technology using HSP sound wave reflection method,which has guided anchor hole construction successfully.Through introducing the basic principle,testing apparatus and the related software system,and testing method of sound wave technology,the forecast result is compared to the test result and the accuracy of forecast result is verified.It is indicated that this method can be widely applied in the similar underground engineering. |
