Several soil stabilization techniques have been adopted to favorably modify the geotechnical properties like hydraulic conductivity, strength, and compressibility of soil. In this study, xanthan gum (XG), an anionic bacterial extracellular polysaccharide is used to modify the geotechnical properties of the soil, particularly its strength and hydraulic conductivity. The addition of xanthan gum to s...... hiện toàn bộ
A multilevel parallel bonded-grain based model (Multi Pb-GBM) accounting for microstructure failures of typical crystalline rocksBulletin of Engineering Geology and the Environment - Tập 81 - Trang 1-14 - 2022
G. Li, S. Q. Liu, F. S. Ma, J. Guo
This study investigates the mechanical properties of rock material at the grain scale. A multilevel parallel bonded-grain based model (Multi Pb-GBM) is proposed to revel the microstructure of granite. The bonded modes of the samples are classified into three types: intra-grain contacts, inter-grain contacts between the same type of mineral, and inter-grain contacts between two different minerals. ...... hiện toàn bộ
Simulating the process of the Jinshajiang landslide-caused disaster chain in October 2018Bulletin of Engineering Geology and the Environment - Tập 79 - Trang 2189-2199 - 2020
Wei Liu, Nengpan Ju, Zhen Zhang, Zheng Chen, Siming He
A mountain disaster chain always brings about potential danger to the safety of people and the environment based on its characteristics of long time-scale, great destructive power, and broad scope. Mechanisms responsible for this hazard are represented by studying a landslide-caused disaster chain that occurred in the bank of Jinshajiang River, China on 10 October 2018. The evolution process of th...... hiện toàn bộ
Physical and numerical modeling on the failure mechanism of landslides with a wall-like locking sectionBulletin of Engineering Geology and the Environment - Tập 82 - Trang 1-17 - 2023
Dong-Dong Li, Han-Dong Liu, Su-zhen Duan, Zheng Geng
Landslides with a wall-like locking section can fail rapidly, resulting in a substantial loss of life and property. Clarifying the failure mechanism and evolutionary criteria of such landslides is vital for improving prediction and preventing of such disasters. Such clarification can be done efficiently using physical model tests. In this study, large-scale models were constructed to test the effe...... hiện toàn bộ
Classification des granulats pour les couches de roulement des chausseesBulletin of Engineering Geology and the Environment - Tập 30 - Trang 119-121 - 1984
Adolf G. Pokorny
La résistance au polissage dépend surtout d'une certaine micro-rugosité du grain du granulat qui est considérée comme une qualité plus ou moins naturelle de la roche liée à sa composition minéralogique, tandis que la résistance mécanique peut être influencée par la méthode d'exploitation et la technologie de la production. Il est nécessaire de prendre en considération que la connaissance de la rés...... hiện toàn bộ
Potential hazards to a tunnel caused by adjacent reservoir impoundmentBulletin of Engineering Geology and the Environment - Tập 78 - Trang 397-415 - 2017
Bin Zhang, Han-xun Wang, Yi-wei Ye, Jun-liang Tao, Lian-ze Zhang, Lei Shi
A reservoir impoundment located near a tunnel structure negatively affects groundwater seepage to varying degrees. This can result in water inflow, structural collapse, and other engineering hazards during tunnel excavation. In addition, in cold regions, reservoir impoundment and water seepage can exacerbate frost heave damage during tunnel operations. This paper describes a comprehensive case stu...... hiện toàn bộ

Geotechnical characterization of a clay–cement mixBulletin of Engineering Geology and the Environment - Tập 72 - Trang 601-608 - 2013
Ramy Saadeldin, Sumi Siddiqua
Soft clay deposits are highly plastic, normally consolidated fine grained soils characterized by their low inherent shear strength. The mixing of soft clays with cement as a chemical stabilizer has become a well-known stabilization technique. The resulting strength of the clay–cement mix is controlled by different factors, but mainly the water to cement ratio, the cement content, and the curing co...... hiện toàn bộ
