The anti-seismic problem of rural residential buildings is the weak link seismic retrofitting in China. Recently, geotechnical isolation (GSI) technology based on rubber-sand mixtures (GSI-RSM) using (RSM) between structural foundation and soil has been proven to have possibility potential applications buildings. Many theoretical studies exist effectiveness GSI-RSM system, but few either response test model placed RSM layer or large-scale shaking table exist. Therefore, this study considers a large performed 1/4 single-story masonry structure with without system by selecting standard input ground motion varying acceleration amplitudes. results show that can reduce superstructures. effect low small earthquakes increases increasing earthquake magnitude. Overall, filter part high-frequency components transmit superstructure consume more energy generating friction slip interaction foundation.

Finding new, effective predictive variables for 3D mineral prospectivity modeling is both important and challenging. The ore-forming numerical quantitively characterizes the complex coupling-mineralization process of structure, fluid, heat, wall rock, which may be potential indicators exploration. We here conducted with integration computational simulation information in Xiadian orogenic gold deposit, China, to examine whether data input can improve reliability modeling. First, we constructed models orebody fault extract geometric features using spatial analysis, as they are always considered crucial controls distribution. Second, performed deformation–fluid–heat-coupling structurally controlled hydrothermal Au system FLAC3D platform. Finally, fault-geometry (buffer, dip, dip variation, undulation) ore-formation-simulation indices (volume strain, shear temperature fluid flux) were integrated Bayesian decomposition modeling, has a promising nonlinear model ability flexible variable-integration ability. results demonstrated that generated by combining geometry achieved significantly higher AUC, precision, accuracy, Kappa, F1 scores compared other single-predictor-variable dataset. This suggests joint use construct comprehensive association between its ore-controlling factors, thereby resulting highly reliable model. Thus, approach aided proves more useful guiding exploration, especially condition fewer variables. Based on outcomes, identified four targets at depth district warrant focused exploration efforts.
