Enhancing the geotechnical properties of soil using xanthan gum—an eco-friendly alternative to traditional stabilizers
Bulletin of Engineering Geology and the Environment - Tập 80 - Trang 1157-1167 - 2020
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...
A multilevel parallel bonded-grain based model (Multi Pb-GBM) accounting for microstructure failures of typical crystalline rocks
Bulletin of Engineering Geology and the Environment - Tập 81 - Trang 1-14 - 2022
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. ...
Simulating the process of the Jinshajiang landslide-caused disaster chain in October 2018
Bulletin of Engineering Geology and the Environment - Tập 79 - Trang 2189-2199 - 2020
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...
Sự tương liên đa biến giữa các đặc tính địa kỹ thuật và địa chất thuỷ văn để phát triển các cụm lithology gần bề mặt trong địa hình trầm tích Dịch bởi AI
Bulletin of Engineering Geology and the Environment - Tập 81 - Trang 1-24 - 2022
Nghiên cứu báo cáo phương pháp liên kết các yếu tố địa kỹ thuật và địa chất thuỷ
văn để phát triển các cụm lithology gần bề mặt trong một địa hình trầm tích. Các
phép đo địa vật lý, địa kỹ thuật và địa chất thuỷ văn được thực hiện tại hiện
trường và trong phòng thí nghiệm nhằm tìm ra các mối tương quan giữa các yếu tố
liên quan, nhóm các yếu tố thành các cụm theo độ sâu và xác định mối tương quan

Physical and numerical modeling on the failure mechanism of landslides with a wall-like locking section
Bulletin of Engineering Geology and the Environment - Tập 82 - Trang 1-17 - 2023
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...
Classification des granulats pour les couches de roulement des chaussees
Bulletin of Engineering Geology and the Environment - Tập 30 - Trang 119-121 - 1984
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...
Potential hazards to a tunnel caused by adjacent reservoir impoundment
Bulletin of Engineering Geology and the Environment - Tập 78 - Trang 397-415 - 2017
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...
Geotechnical characterization of a clay–cement mix
Bulletin of Engineering Geology and the Environment - Tập 72 - Trang 601-608 - 2013
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...
