  • Deformation mechanism of surrounding rock in weakly cemented thick coal seam roadways and research on graded anchor composite support technology

    Deformation mechanism of surrounding rock in weakly cemented thick coal seam roadways and research on graded anchor composite support technology

    Model construction

    To investigate the deformation and failure characteristics of the surrounding rock during the excavation of the 11,703 transportation roadway, a numerical model was developed using FLAC3D based on the borehole columnar section….

  • Study on an interpretable prediction model for pile bearing capacity based on SHAP and BP neural networks

    Study on an interpretable prediction model for pile bearing capacity based on SHAP and BP neural networks

    BP neural network

    The Backpropagation (BP) neural network model is a multilayer feed-forward architecture that comprises an input layer, one or more hidden layers, and an output layer. This computational algorithm employs error backpropagation as…

  • The analysis of the progressive local failure process of the Longquan Reservoir dam based on the global-local dynamic strength reduction method

    The analysis of the progressive local failure process of the Longquan Reservoir dam based on the global-local dynamic strength reduction method

    The safety stability factor of slopes (dams) is determined using the finite element strength reduction method. The basic principle involves iteratively reducing strength parameters, such as cohesion c and φ, until the slope (dam) reaches a…
