...Qaisar Abbas; Jonghyeog Yoon; Hyunil Shin; Junhwan Lee In this study, the influence of surface loading on wall and ground behaviour for deep excavations was investigated. Centrifuge tests and finite-element analyses were performed to characterise the effects of various surface loading components...

With the increasing urban building density, it is becoming more...

...Xianfeng Ma, PhD; Mingyang Cao, MS; Liang Zhang, BS; Lei Wang, PhD, PE A modified tool for simulating the entire process of supported excavation in centrifuge modelling was developed based on a Cambridge type of excavating system. Utilising the modified tool, a series of centrifuge tests of braced...

...R. J. Goodey, BEng, PhD; S. Divall, MEng, PhD, CEng; B. T. Le, BEng, PhD Shafts are frequently constructed to allow access to subsurface infrastructure and the resulting excavation is generally deep and narrow. Shafts may be constructed using a variety of methods and plan forms dependent on ground...

... are averaged from those of the rock strata above the excavations in salt at 250 m depth. This depth represents most of the mine horizon in the Maha Sarakham salt formation. Table 2 shows the mechanical and physical properties and thicknesses of the strata for the three rock sequences. These properties...

...Feng Yu, PhD; Zheng-bing Xie, MSc; Nuo Duan, PhD; Nian-wu Liu, PhD; Hua-feng Shan, PhD Further excavation beneath constructed underground space offers a material-saving solution to supplement vertically utilisable space in developed urban regions. Under such circumstances, the existing and newly...

...Mohsen Sabermahani, PhD; Faraz Ahimoghadam, MSc; Valiollah Ghalehnovi, MSc The current research was undertaken to study the effect of surcharge magnitude on soil-nailed wall behaviour by modelling an excavation using a geotechnical centrifuge and analytical software. An acceleration of 50g...

...A.M. McNamara; R.J. Goodey; R.N. Taylor The construction of deep basements in urban areas is associated with many risks and problems among Which is the possible damage to existing structures and services resulting from settlements near the excavation. A number of methods are routinely employed...

...T. H. Tefera; S. Nordal; L. Grande; R. Sandven; A. Emdal The ground settlement and wall deformation of a sheet pile wall during different stages of excavation have been studied using a large scale model test in a bin with dry sand at the Norwegian University of Science and Technology, NTNU...

...Christophe Gaudin; Jacques Garnier; Luc Thorel Centrifuge modelling is henceforth a recognized experimental technique. Its use for study of retaining wall was until now slowed down by the necessity to carry out in-flight excavation in order to model correctly the stress history in the structure...
