TLDR
The PFC∼2D numerical calculation model of soil-rock mixtures is established and the results show that when the stone content is 80%, the analysis should be caused by the large amount of rock, which leads to the large internal voids, and the sudden unloading between the rock and the rock during compaction and then the structural reorganization.About:

Research on gas leakage and collapse in the cavern roof of underground natural gas storage in thinly bedded salt rocks
TL;DR: In this paper, the gas leakage through a cavern roof and the induced collapse are investigated in bedded salt rocks, and a numerical simulation model is established based on the geo-conditions of the ZJ-block.

Human–computer interaction-based Decision Support System with Applications in Data Mining
TL;DR: A new visual decision-making system applicable for industrial applications, i.e. data mining topics, designed for data mining technique applications is proposed and shows that the proposed method is effective and robust in comparison to other methods.

Application of the discrete element method and CT scanning to investigate the compaction characteristics of the soil–rock mixture in the subgrade
TL;DR: The soil-rock mixture (SRM) usually contains a large amount of gravels exceeding 40 mm in size, so the traditional laboratory method cannot directly test its maximum dry density (MD), making it dif...

A 2D FDEM-based moisture diffusion–fracture coupling model for simulating soil desiccation cracking
TL;DR: Based on the combined finite-discrete element method (FDEM), a moisture diffusion-fracture coupling model was proposed in this article to simulate soil desiccation cracking, where the shrinkage stress caused by the change of moisture content was calculated and applied to the system equation.

Correlational Analytical Characterization of Energy Dissipation-Liberation and Acoustic Emission during Coal and Rock Fracture Inducing by Underground Coal Excavation
TL;DR: In this paper, the authors used an acoustic emission (AE) test to examine the energy dissipation and liberation of coal and rock fracture due to underground coal excavation and found that the relevant mechanical parameter discreteness was too large because the internal structures of the coal and the rock were divided into multiple structural units (MSU) by a few main cracks.

Chloride Adsorption by Calcined Layered Double Hydroxides in Hardened Portland Cement Paste
Seyoon Yoon,Juhyuk Moon,Sungchul Bae,Xiaonan Duan,Emmanuel P. Giannelis,Emmanuel P. Giannelis,Paulo José Melaragno Monteiro +6 more
TL;DR: In this paper, the feasibility of using calcined layered double hydroxides (CLDHs) to prevent chloride-induced deterioration in reinforced concrete was investigated and shown that they not only adsorbed chloride ions in aqueous solution with a memory effect but also had a much higher binding capacity than the original layered double hydrides (LDHs) in the cement matrix.
