Kriging-based reliability analysis of the long-term stability of a deep drift constructed in the Callovo-Oxfordian claystone
Autor: Ngoc-Tuyen Tran, Duc-Phi Do, Dashnor Hoxha, Minh-Ngoc Vu, Gilles Armand
Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 13, Iss 5, Pp 1033-1046 (2021)
Callovo-Oxfordian (COx) claystone has been considered as a potential host rock for geological radioactive waste disposal in France (Cigéo project). During the exploitation phase (100 years), the stability of drifts (e.g. galleries/alveoli) within th

Probabilistic Stability Analysis of Deep Rock Tunnel Excavated by Mechanized Tunneling Considering Anisotropic Initial Stresses
Autor: Duc Phi Do, Xiangfeng Guo, Daniel Dias
Publikováno v: Applied Sciences, Vol 12, Iss 15, p 7479 (2022)
Due to the complex geological conditions, the construction of underground tunnels in the rocks exhibiting creep behaviors is a great challenge and the structures’ long-term stability is of main importance. The excavation by tunnel boring machines (

Effective Elastic and Hydraulic Properties of Fractured Rock Masses with High Contrast of Permeability: Numerical Calculation by an Embedded Fracture Continuum Approach
Autor: Hong-Lam Dang, Duc Phi Do, Dashnor Hoxha
Publikováno v: Advances in Civil Engineering, Vol 2019 (2019)
In this work, the hydromechanical modeling of the fractured rock masses was conducted based on a new numerical simulation method named as embedded fracture continuum (EFC) approach. As the principal advantage, this approach allows to simplify the mes

Effect of spatial variability of creep rock on the stability of a deep double-lined drift
Autor: Gilles Armand, Minh-Ngoc Vu, Dashnor Hoxha, Duc-Phi Do, Tran Ngoc Tuyen
Publikováno v: Journal of Science and Technology in Civil Engineering (STCE) - HUCE. 16:46-58
This work aims at investigating the effect of aleatoric uncertainty of creep rock properties on the stability of an underground structure. This uncertainty relates to the spatial variability of the mechanical parameters representing the time-dependen

Modified AK-MCS method and its application on the reliability analysis of underground structures in the rock mass
Autor: Gilles Armand, Minh-Ngoc Vu, Dashnor Hoxha, Duc-Phi Do, Ngoc-Tuyen Tran
Publikováno v: Journal of Science and Technology in Civil Engineering (STCE) - HUCE. 16:38-54
This work aims at proposing the methodology on the basis of the extension of the famous reliability analysis, joining the Kriging and Monte Carlo Simulation (AK-MCS) metamodeling technique for analyzing the long-term stability of deep tunnel support

Time-Dependent Behavior of Callovo-Oxfordian Claystone for Nuclear Waste Disposal: Uncertainty Quantification from In-Situ Convergence Measurements
Autor: Duc-Phi Do, Ngoc-Tuyen Tran, Dashnor Hoxha, Minh-Ngoc Vu, Gilles Armand
Publikováno v: Sustainability; Volume 14; Issue 14; Pages: 8465
The sustainability of geotechnical infrastructures is closely linked with their long-time behavior. In fact, there is not a straightforward procedure to predict this behavior, and very often, the back analyses of observed data are the best tool to un
