Abstract: Macroscopic mechanical properties of engineering rock mass, especially the maximum load-bearing capacity is one of the most basic and difficult task of rock mechanics. The effect of the lateral pressure on maximum load-bearing capacity of rock block investigated numerically, the relations between lateral pressure and the maximum load-bearing capacity are acquired, the acoustic emissi on rules of rock block with the change of lateral pressure are found out, which is practially beneficial for the research on the macroscopic mechanical properties of rock mass.
Keyword: rock block, heterogeneity, maximum load-bearing capacity, numerical simulation.
