Multi-scale simulation of wave propagation and liquefaction in a one-dimensional soil column: hybrid DEM and finite-difference procedure
Acta Geotechnica - - 2022

Probabilistic stability assessment using adaptive limit analysis and random fields
Acta Geotechnica - Tập 12 - Trang 937-948 - 2016
Abid Ali, A. V. Lyamin, Jinsong Huang, J. H. Li, M. J. Cassidy, S. W. Sloan
For deterministic scenarios, adaptive finite element limit analysis has been successfully employed to achieve tight bounds on the ultimate load of a geotechnical structure in a much more efficient manner than a dense uniform mesh. However, no probabilistic studies have so far considered finite element limit analysis with adaptive remeshing. Therefore, this research explores the benefits of combin...... hiện toàn bộ
Numerical study of partially drained penetration and pore pressure dissipation in piezocone test
Acta Geotechnica - Tập 12 - Trang 195-209 - 2016
Francesca Ceccato, Paolo Simonini
The piezocone penetration test (CPTU) is commonly used as a fast and economical tool to identify soil profile and to estimate relevant material properties in soils ranging from fine to coarse-grained. Moreover, in the case of fine-grained soils (clays and silts), the consolidation coefficient and the permeability can be estimated through the dissipation test. Undrained conditions are commonly assu...... hiện toàn bộ
Sự tiến hóa ba chiều của hư hỏng trong đĩa sa thạch Brazil qua việc sử dụng đồng thời các kỹ thuật siêu âm chủ động và thụ động Dịch bởi AI
Acta Geotechnica - Tập 15 - Trang 393-408 - 2018
Shihuai Zhang, Shunchuan Wu, Guang Zhang, Pei Guo, Chaoqun Chu
Các kỹ thuật siêu âm chủ động và thụ động đã được sử dụng để nghiên cứu sự tiến hóa ba chiều của hư hỏng trong các đĩa sa thạch dưới thử nghiệm Brazil. Một đĩa tiêu chuẩn, có đường kính 50 mm và độ dày 25 mm, đã được trang bị một mảng cảm biến 3D gồm 12 cảm biến Nano30 và bị nén đường kính dưới tải trọng tuyến tính một cách tĩnh. Tốc độ sóng P dọc theo 64 đường đi trong mẫu đĩa đã được đo trước và...... hiện toàn bộ

Impermeable and mechanical stability of filter cake under different infiltration conditions via CFD-DEM
Acta Geotechnica - - 2023
Fan Chen, Hao Xiong, Zhen-Yu Yin, Xiangsheng Chen
The slurry infiltration process contributes significantly to the stability of tunnelling face during the application of slurry pressure balanced tunnel boring machine (SPB TBM) in construction. A coupled computational fluid dynamics and discrete element method (CFD-DEM) model is developed to simulate the formation and long-term impermeable stability of filter cake considering different infiltratio...... hiện toàn bộ
Influence of matric suction on nonlinear time-dependent compression behavior of a granular fill material
Acta Geotechnica - Tập 15 Số 3 - Trang 615-633 - 2020
Wen Bo Chen, Kai Liu, Wang Feng, Lalit Borana, Jian‐Hua Yin
Measurement of three-dimensional shrinkage deformations and volumes of stabilised soft clay during drying with Structure from Motion photogrammetry
Acta Geotechnica - Tập 18 - Trang 5319-5339 - 2023
Zhong-Sen Li, Leena Korkiala-Tanttu, Wojciech Sołowski
The paper applies the Structure from Motion photogrammetry technique to measure three-dimensional shrinkage deformations of a cylindrical specimen during drying. A clay–binder mixture was statically compacted, and its shrinkage behaviour was observed for four weeks with a newly established photogrammetric system. The complete surface information including XYZ coordinates and RGB values was then re...... hiện toàn bộ
An insight into grain interaction in bentonite/claystone mixtures
Acta Geotechnica - Tập 18 - Trang 573-579 - 2022
Zhixiong Zeng, Yu-Jun Cui, Jean Talandier
This paper investigates the swelling mechanism of Callovo-Oxfordian (COx) claystone grain in its mixtures with bentonite which are potential candidate for engineered barriers in the French high-level radioactive waste disposal. The swelling pressures of MX80 bentonite/COx claystone mixtures with various bentonite fractions and dry densities were first experimentally determined by carrying out infi...... hiện toàn bộ
Evaluating the effect of active ions on the early performance of soft clay solidified by modified biomass waste-rice husk ash
Acta Geotechnica - Tập 18 - Trang 1039-1056 - 2022
Ruifeng Chen, Surya Sarat Chandra Congress, Guojun Cai, Ruixian Zhou, Jingmin Xu, Wei Duan, Songyu Liu
Soft clay generally cannot be directly used as subgrade material due to its poor engineering characteristics. The application of rice husk ash (RHA) for the solidification of problematic soil contributes to the recycling of waste and reduces carbon emissions. A series of mechanical, chemical, and microscopic tests were conducted to assess the early effectiveness of RHA in stabilizing soft clay. Th...... hiện toàn bộ
Microstructural evolution of expansive clay during drying–wetting cycle
Acta Geotechnica - Tập 15 - Trang 2355-2366 - 2020
Tiantian Ma, Changfu Wei, Chuanqin Yao, Panpan Yi
This paper presents a comprehensive investigation on the microstructural evolutions of expansive clay during a drying–wetting cycle, including pore size distribution (PSD) via mercury intrusion porosimetry and water distribution via nuclear magnetic resonance (NMR). The soil water characteristic curves at different soil densities and soil shrinkage curve are also obtained, and a threshold suction ...... hiện toàn bộ
