    APPLICATION OF AN ELECTRICAL METHOD BEAM|FOR ADVANCED GEOLOGICAL EXPLORATION TO TUNNELING IN TONGLUO MOUNTAINS FOR DIAN-LIN HIGHWAY

    • The BEAM is a new kind of electrical method that is used in advanced geological exploration during tunneling It has been rarely used in China. This paper firstly introduces the operation principle of the BEAM technique, and then discusses the first application to the tunneling in TongLuo Mountain for Dian-Ling highway. The detailed work process and results are presented. Comparison among the results of BEAM, GPR, TSP and the actual case after cutting indicates that BEAM has a fairly good efficiency when there is ground water in the rock mass ahead of tunnel work face. At last, some advice is summarized on how to use this method in China.
