A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, EarlyView.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Toward Zero Waste Mining: Circular Economy of Copper Slags

Global Challenges, EarlyView.
Mining and metal extraction processes generate over 90% of global waste. With the rapid increase in population and urbanization, the demand for geotechnical applications and construction materials constantly increases and can absorb the entire quantity of slags generated.

The detection and tracking of mine-water pollution from abandoned mines using electrical tomography [PDF]

, 2009
Increasing emphasis is being placed on the environmental and societal impact of mining, particularly in the EU, where the environmental impacts of abandoned mine sites (spoil heaps and tailings) are now subject to the legally binding Water Framework and ...

A Novel Autoencoder Variant for Predicting 3D Printing Parameters From Geometric and Consumption Constraints

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In recent years, the field of 3D printing has heavily relied on expert knowledge and complex trial‐and‐error procedures to determine appropriate printing parameters that meet desired consumption specifications. This study introduces a novel method for predicting 10 printing parameters based on 7 geometric features and 3 target consumption ...

HOW TO BENEFIT FROM EARTHQUAKES

e-Zbornik. Elektronički Zbornik Radova Građevinskog Fakulteta
Earthquakes are natural events and it is quite easy and beneficial to convert them to wealth (national asset) rather than catastrophe. The earthquakes exert their catastrophe on the buildings/structures founded in soil grounds. There is not even a single

Overview geotechnical model tests on dike safety at Deltares [PDF]

, 2012
Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed.

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...
