Abstract:

To quickly and accurately predict the compressive strength of concrete, a prediction model is established using deep learning technology. The model is automatically optimized and adjusted using the Bayesian optimization algorithm, and the prediction results are analyzed by combining with the SHapley Additive exPlanations (SHAP) interpretable method, which overcomes the problem of the “black box” of the prediction model. The deep learning model is used to mine the potential law between each input feature parameter and compressive strength, the importance of the parameters on the compressive strength prediction results and the influence law is analyzed by visualizing the SHAP values of the input feature parameters. The results show that the constructed deep learning model outforms other traditional models. The SHAP analysis results are consistent with the experimental results, and the model better reflects the complex nonlinear relationship among the characteristic parameters, which can provide the basis and reference for the engineering design of concrete materials.
