Summary: The intact rock elastic modulus (E) is a key parameter in the design of projects related to rock mechanics and engineering geology. This study aims to evaluate the effectiveness of two meta-heuristic-driven approaches, ANFIS-DE and ANFIS-FA, in predicting E. The ANFIS-FA model outperformed ANFIS-DE, ANFIS, and NN models in terms of predicting E value, based on data collected from the Azad and Bakhtiari dam sites in Iran. Sensitivity analysis showed that P-wave velocity had a larger influence on E compared to other independent variables.

Summary: The study found that the compressive strength of sandstones decreases with increasing grain size, while the confined compressive strength declines with increasing porosity. Sandstones with grains larger than 250 μm show a decrease in UCS, while those with grains smaller than 250 μm exhibit an enhancement in UCS. Additionally, sandstones with higher fractal dimensions and poorer sorting tend to have larger UCS.

Summary: The research in lacustrine rift basins in Eastern China found that the organic matter in deep formations mainly comes from a mix of aquatic microorganisms and higher plant materials, with higher plant materials being dominant. The bio-productivity was moderate to high, the paleoclimate was mainly cold and semi-humid to semi-arid, lake salinity ranged from fresh to brackish-water, and redox conditions were sub-reducing to sub-oxidizing. The dilution degree was strongest in the Yingcheng shale, followed by the Shahezi and Huoshiling formations.

Summary: This study introduces a Bayesian approach for characterizing the correlation between uniaxial compressive strength (UCS) and Youngs' modulus (E) of rock. The approach does not require the use of an empirical model and is data-driven, using limited UCS and E data pairs and their prior information to generate samples for analysis of marginal statistics, distributions, and correlation. The results show that the approach is effective in characterizing the correlation and can be used in sites with limited data.

Summary: This paper proposes an alternative prediction technique for Poisson's ratio in rock geomechanical properties using real-time drilling parameters. The method utilizes drilling data and three machine-learning methods, namely support vector machine, functional network, and random forest.

Summary: A new method of multi-sensor signal analysis based on PARAFAC and SVM is proposed for fault diagnosis of centrifugal pump. The method utilizes CWT for time-frequency representation of single-channel vibration signal and constructs a three-dimensional data matrix. The proposed 3-level PARAFAC method is used to decompose the matrix and obtain features from both time and frequency domains. Experimental results show that the method has better performance in processing big data with multiple sources.

Summary: The shape of tailing particles is crucial for their macroscopic mechanical properties. This study investigates the macro-mesoscopic response of heteromorphic tailing particles using multisphere approximation and numerical simulation. The research reveals the relationship between mesostructure evolution and macroscopic engineering characteristics of heteromorphic tailing particles. The results show that changes in angularity affect particle rearrangements, porosity, and stress characteristics. The study also suggests that rigid boundary simulations are feasible for macroscopic mechanical behaviors. These findings provide important insights into the response and mechanical mechanisms of nonspherical particles and can be applied in microscopic simulations of tailings.

Summary: A uniaxial strain-softening constitutive model for fiber-reinforced soils is developed based on the disturbed state concept. The model considers the response in the intact state and fully adjusted state, and the apparent stress-strain curve is derived from a weighted average of these two responses. The model demonstrates that fiber content has a greater influence on reinforcement effect than fiber length. Evaluation of test data shows that the model predicts stress-strain curves in good agreement with experimental results, and accurately describes the fiber reinforcement effect.

Summary: The influence of cyclic weak disturbance on the stress relaxation of rock depends on the initial stress level and axial strain level, showing different nonlinear growth characteristics. Initially, the relaxation magnitude of weak disturbance increases with the increase of the initial stress level, while the stress relaxation rate nonlinearly decreases with axial strain levels. The weak disturbance effect presents a nonlinear growth characteristic of first decreasing and then increasing as the strain increases.
