基于GRNN的广义折减法在岩爆预测中的应用

With the rock burst hazard is increasing, In order to quantitatively obtain the safety coefficient from the the higher rockburst intensity of one surrounding rock's state that is under rock burst dangerous state, put forward a new method. Through the further application of strength reduction method that is widely used in slope engineering, and combining with the intelligent algorithm, established a theoretical model of generalized reduction method based on GRNN. Based on analysis of the rock burst genesis, selected the factors that influence rock burst, and as the input parameters of the GRNN model. Through rock mechanics theory, selected the uniaxial compressive strength and the uniaxial tensile strength two impact factors for reduction. Through the examples show that, the generalized reduction method can simply calculate safety coefficient of one surrounding rock's state from the the higher rockburst intensity.
