The espresso extraction process involves a complex transport inside geometry-changing porous medium. Large solid grains forming the majority of medium can migrate, swell, and consolidate, they also morphologically change during flow, i.e., being mechanically eroded by hydrodynamic forces. These processes can, in turn, have significant back-effect on flow related coffee profiles. In this article...

Mudstone is a widely occurring type of rock in deep mining, and it crucial to understand its failure mechanisms strength characteristics under the interaction water high stress ensure stability deeply buried engineered mudstone. In this study, composition structure mudstone were obtained, triaxial tests conducted on five different contents four confining pressures using servo press. The variati...

We investigated the impact of water weakening on mechanical behavior Obourg Chalk and Ciply (Mons Basin, Belgium). Different tests were conducted to estimate unconfined compressive strength (UCS), tensile strength, Young’s modulus, under triaxial loading, critical pressure, fracture toughness, cohesion, internal friction coefficient samples either dry or saturated with brine. This extensive dat...

The analysis of mechanical response and deformation-cracking behavior contributes to the high-efficiency extraction geo-energy long-term safety underground engineering structures. Compared natural cores, properties 3D-printed samples made from quartz sand as raw material are relatively homogeneous, can be used for quantitative studies on influence defects rocks. In this work, with single fractu...

Used tires are unwanted wastes especially in urban areas and their extent is growing every year. With the development of human societies increasing use automobiles, year millions used collected as garbage around world leave consumption cycle. However, they can be by mixing with soil, one basic building materials, to improve mechanical properties. This article discusses effect adding tire chips ...

Material properties is one of the most significant variables in terms efficiency. The sediment layer a coal pit mine has possibility sticking to equipment bucket and reducing its productivity, especially disposal area. Consequently, stickiness close definition adhesivity level; thus it may be associated with geomechanical properties. Various soil classification area was investigated identify re...

To investigate the seismic response characteristics of piled wharf structures, a numerical model soil-structure interaction system is established. Extensive fiducial error and grey correlation analyses are also conducted to obtain degree sequence internal force structure deformation, as well acceleration surrounding soils. The results show that peak at typical point soil more sensitive variatio...

Determination of soil shear strength is essential for engineering construction. Using rice husk ash (RHA) with cement in the a potential ground improvement technique that can reduce environmental problems and construction budget. In present study, ten combinations soil-RHA-cement were investigated to understand effects RHA on parameters soil. The admixtures prepared by taking 5%, 10%, 15% RHA, ...

In order to deeply study the mechanism of prestressed anchor anti-slide pile, an indoor model experimental device was developed, and a finite difference particle flow numerical analysis slope cable pile established based on reinforcement project in mountain road slope. Based force displacement characteristics influence prestress cable, inclination angle width column spacing landslide, height na...

Earth reinforcing techniques have become useful and economical to solve problems related to difficult grounds and provide satisfactory foundation performance. In this context, this paper uses radial basis function neural network (RBFNN) for predicting the bearing pressure of strip footing on reinforced granular bed overlying weak soil. The inputs for the neural network models included plate wid...
