Given the critical role of true triaxial strength assessment in underground rock and soil engineering design construction, this study explores sandstone using data-driven machine learning approaches. Fourteen distinct test datasets were collected from existing literature randomly divided into training (70%) testing (30%) sets. A Multilayer Perceptron (MLP) model was developed with uniaxial compressive (UCS, σc), intermediate principal stress (σ2), minimum (σ3) as inputs maximum (σ1) at failure output. The optimized Harris hawks optimization (HHO) algorithm to fine-tune hyperparameters. By adjusting structure activation function characteristics, final made continuously differentiable, enhancing its potential for numerical analysis applications. Four HHO-MLP models different functions trained validated on set. Based comparison prediction accuracy meridian plane analysis, an high predictive meridional behavior consistent theoretical trends selected. Compared five traditional criteria (Drucker–Prager, Hoek–Brown, Mogi–Coulomb, modified Lade, Weibols–Cook), demonstrated superior performance both datasets. It successfully captured complete variation space, showing smooth continuous envelopes deviatoric planes. These results underscore model’s ability generalize across conditions, highlighting a powerful tool predicting geotechnical
