Abstract To propose an effective and reasonable excavation plan for rock joints to control the overall stability of surrounding mass predict prevent engineering disasters, this study is aimed at predicting joint shear strength using combined algorithm by support vector regression (SVR) firefly (FA). The dataset collected was employed as output prediction, roughness coefficient (JRC), uniaxial compressive (σc), normal stress (σn), basic friction angle (φb) input machine learning. Based on...
Uranium mining waste causes serious radiation-related health and environmental problems. This has encouraged efforts toward U(VI) removal with low cost high efficiency. Typical uranium adsorbents, such as polymers, geopolymers, zeolites, MOFs, their associated costs limit practical applications. In this regard, work found that the natural combusted coal gangue (CCG) could be a potential precursor of cheap sorbents to eliminate U(VI). The efficiency was modulated by chemical activation under...
Pervious concrete (PC) is at risk of clogging due to the continuous blockage sand into it during its service time. This study aims evaluate and predict such behavior PC using hybrid machine learning techniques. Based on 84 groups dataset developed in earlier study, was determined by algorithm combing SVM (support vector machines) particle swarm optimization (PSO) methods. The PSO employed adjust hyperparameters verify performance 10-fold cross-validation. predicting results model were...
Fissures and holes widely exist in rock mechanics engineering, and, at present, their failure mechanisms under complex compress shear stress states have not been well recognized. In our work, a fracture mark, ξ, is introduced, the kernel function of smoothed-particle hydrodynamics (SPH) then re-written, thus realizing modelling media. Then, numerical models containing fissures are established, progressive processes simulated, with results showing that: (1) improved SPH method can reflect...
A systematic study of the stacking fault energy (?SF) for dilute Al-based alloys (Al23X, Al47X and Al71X, where X = Al, Ag, Be, Ca, Cd, Co, Cu, Cr, Fe, Ga, Ge, Hf, In, K, La, Li, Mn, Mg, Ni, Na, Pb, Sc, Sn, Sr, Si, Ti, V, Zn, Zr) has been performed by means first-principles calculations. Alias shear deformation is adopted in present investigations. The presently calculated ?SF Al favorable accordance with experimental other theoretical data. For targeted elements, calculations indicate that...
In this study, the numerical direct shear tests were conducted to investigate mechanical properties of joint networks under constant normal stiffness (CNS) boundary conditions. The influence random number on stress (τ), dilation (normal displacement, δv) and (σn) rock mass studied quantitatively with fixed main slip surface. At same time, internal evolution process failure analyzed. results reveal that joints (γ) has little effect stresses. displacement sample generally decreases as...
The stress inside and outside the traditional cross-section angle steel in transmission lines are uneven, resulting deviation of actual carrying capacity theoretical design value. This paper proposes use improved splicing form to improve structure’s mechanical properties. Two spliced forms multiple analyzed by finite element simulation analysis, so as compare two different forms’ coordination component displacement, uniform force, status on maximum control section. It is pointed out that...
Abstract The sensitivity analysis of F reservoir in M area is carried out by core laboratory experiment. experimental results show that this belongs to medium weak-strong water sensitivity, strong acid and alkali its speed very weak, basically weak-no sensitivity. Through analysis, it provides a basis for rational selection injection fluid area.
