The autor introduces the study of geological advanced prediction as well as the principle,deal with date and explain technique of TSP20 in this paper,and application of TSP20 for geological advanced prediction in XUE FENG SHAN tunnel as well.
This paper describes necessity and importance of geological advance forecast and introduces composition and detection principle of PUSLE-EKKO series Geologic Radar system. It takes instances to illustrate the application of PUSLE-EKKO Geologic Radar in road tunnel construction.
Research methods:With the background of work experience of the author himself on Bapanling and Changliangshan Tunnel,the important role and significance of geological forecast on construction of long-large tunnel in railway,highway and urban rail transportation in China are emphasized in this paper.
In the course of construction of this project, not only the drilling and blasting method and shotcrete technology, but also many other methods and technologies have been adopted, such as monitoring survey, geologic advance prediction, very large section tunnel construction method, steel fibre reinforced shotcrete technology, drilling carriage with hydraulic steel module for lining construction, and inverted circular arch plate made by steel pipe rolling method.
