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
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

Classification des granulats pour les couches de roulement des chaussees
Bulletin 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
Effect of joint type on the shear behavior of synthetic rock
Bulletin of Engineering Geology and the Environment - Tập 78 - Trang 3395-3412 - 2018
Yifei Cui
The shear behavior of the discontinuities of rock is important because it is closely related to the stability of a rock mass. The scientific challenge lies in the understanding of how different types of joint are related to the failure criterion. In the current study, direct shear tests are used to investigate the shear behavior of continuous planar joints, stepped joints, and discontinuous open j...... hiện toàn bộ
Karst phenomena with gas emanations in Early Oligocene conglomerates: risks within a highway context (Jura, Switzerland)
Bulletin of Engineering Geology and the Environment - Tập 66 - Trang 237-250 - 2006
Frédéric Lapaire, Damien Becker, Romain Christe, Marc Luetscher
During the construction of the A16 motorway, four cavities were discovered in the Early Oligocene carbonate conglomerates of the Jura mountains, northwest Switzerland. One cavity was particularly interesting because of its size and gas emanations. Previous geological works carried out in this key area are summarized, notably the effects of tectonic evolution on the formation of karstic networks. T...... hiện toàn bộ

Numerical study on strength and failure characteristics of rock samples with different hole defects
Bulletin of Engineering Geology and the Environment - Tập 80 - Trang 1523-1540 - 2020
Shaojie Chen, Zhiguo Xia, Fan Feng, Dawei Yin
In a rock mass, holes of various sizes and geometries naturally occur, which in turn can affect the mechanical properties of the rock mass. These defects often cause engineering problems in subsurface construction. In this study, PFC2D was used to perform uniaxial compression tests on a rock mass containing ten different types of hole defects to analyze their failure behavior and mechanical proper...... hiện toàn bộ

Mechanical properties and acoustic emission characteristics of coal samples with a single natural joint of different dip angles
Bulletin of Engineering Geology and the Environment - - 2023
Feng Ju, Dong Wang, Zhongwei Wang, Meng Xiao, Zequan He, Pai Ning, Tengfei Wang, Li Li, Chaoseng Yan, Tao Zhou
The existence of joints reduces the strength of coal and increases the failure probability of coal pillars. To predict and prevent coal pillar failure, it is necessary to clarify the influence of joint dip angle β on coal strength. In this paper, acoustic emission (AE) and unconstrained compression experiments were carried out on coal samples containing a single natural joint with different dip an...... hiện toàn bộ
Volume change behaviour of a saturated lateritic clay under thermal cycles
Bulletin of Engineering Geology and the Environment - Tập 80 - Trang 653-661 - 2020
Charles Wang Wai Ng, Damilola Bashir Akinniyi, Chao Zhou
Many lateritic soils contain goethite and hematite, which have a low thermal expansion coefficient and also enhance the formation of soil aggregates. The influence of these minerals on the thermo-mechanical soil behaviour, however, has not been well understood. In this study, cyclic thermal strain of a small number of specimens of saturated lateritic clay was investigated over a temperature range ...... hiện toàn bộ
