BIM Application Case for Shallow Subway Tunnel Construction
Abstract: Improving productivity through the adoption and development of a new IT technology is becoming a new paradigm in the construction industry. In infrastructure projects, cost reduction through Value Engineering (VE) is becoming the major concern of construction projects. As a result, civil Building Information Modelling (BIM) is being adopted. The application of civil BIM is usually considered as...

Experimental Rock Cutting Tests with Actuated Disc
Abstract: The Actuated disc cutting (ADC) is one of the most state-of-art technologies in the fields of rock cutting mechanics. The ADC is based on the undercutting mechanism, while many cutting parameters are involved in a complex rock cutting process. This paper introduces the new concept of a lab-scaled rock cutting system which can facilitate cutting experiments implemented undercutting concept based...

Risk assessment of shield TBM tunnelling in soft marine sediments
Abstract: Some risks such as machine settlement, jamming, damage of cutters and others are frequently encountered due to the uncertainties of geological and operational factors during subsea shield TBM tunnelling. This paper, thus, focused on the risk assessment of shield TBM tunnelling in adverse ground conditions. Particularly, the correlation between shield TBM settlement and its advance rate was...

Stability analysis of damaged concrete jack lining in an urban cable tunnel
Abstract: In order to minimize environmental impact, semi-shield tunnelling method has been widely applied to construct tunnels for water and sewage, power cable and gas pipe in urban area. In this study, a power cable tunnel was excavated by a semi-shield machine in Suwon, Korea in 2013. Total length of the tunnel is 453 m and the diameter is 2.4 m. During jacking process, unexpected medium rock...
