... and dangerous mountain route in Vietnam using the new Austrian tunnelling method (NATM) - where the first time the twin tunnel was constructed in Viet Nam by drilling and blasting. The special issue in construction is the influence of the safety distance and blasting schemes to each tunnel. The blasting...

... weathering. When cutting hillsides and mountains to construct highways at locations where this type of layered soft rock exists, a new form of slope instability often occurs, which is plane failure in the weak zone or layered surface of the rock mass. In many cases, when surveying and designing...

... in terms of three aspects: casualties, economic losses, and disaster prevention and mitigation ability. Finally, the risk grade of the secondary disasters induced by the earthquake is determined by constructing a risk grade matrix of a mine disaster bearing body. The evaluation method covers numerous...

... Abstract In the construction of pipe-jacking tunnels, simultaneous injecting is a key in controlling surface deformation and jacking force. At present, the traditional simultaneous injecting research is mainly limited to the study of slurry materials and the friction coefficient, while...

... Abstract Unforeseen, challenging ground conditions are a major obstacle for infrastructure development, including tunnel construction. Addressing this risk with traditional, intrusive ground investigations can be costly, sometime prohibitively so. In this paper, we present airborne geoscanning...

... Abstract Building information modeling (BIM) technology realizes the integration of multi-discipline fragment information and visual management and strongly supports tunnel dynamic design and digital construction. However, current BIM platforms, such as Revit, are difficult to establish...

..., the unfavorable temperature field distribution of surrounding rock should be carefully handled in tunnel design and construction. The research results of this paper will provide some reference value for the design and construction of similar tunnel with temperature and heat damage in highland. 1 Introduction...

... Abstract With the deepening of underground excavation, rockburst has become a serious geological disaster, which will always cause casualties, machine damage and delay of construction schedule. Therefore, many scholars at home and abroad have carried out researches on rockburst. Because...
