摘要：
Geology in deep tunnel of Jinping hydropower station is complicated, and its geostatic stress is high. Rockburst occurs too frequently so that construction process is slowly. Rockburst test of Jinping marble is carried out under true triaxial experimental machine system with one surface of the sample unloading suddenly. This paper investigates the phenomena of rockburst using 100mmx40mmx20mm marble specimens. The distribution of marble fractal shows that the main rockburst form of Jinping marble is plate-form damage which relates with working yard. The curves of AE(acoustic emission) energy ratio shows that the type of AE characteristics of marble rockburst is salant: The research results on Jinping marble can provide experimental base for microseismic monitoring technology.
