Extensive research has confirmed the successful prediction of rock mass quality in tunnel boring machine (TBM) construction using machine learning methods based on big data collected during the boring process. However, the developed model cannot be applied to a new project owing to the different mech...
The mud cake is easily formed during the tunnel boring machine (TBM) excavation in clay soils or rocks containing clay minerals. Mud cake will lead to soil disturbance of tunnel face, clogging cutterhead and even affect the construction efficiency and personnel safety. In this study, a discrimina...
Singapore’s Land Transport Authority (LTA) has awarded two civil contracts for the design and construction works of the Cross Island Line Phase 1 (CRL1) at a combined contract value of $766M. The first contract was awarded to Hock Lian Seng Infrastructure Pte. Ltd. for the design and ...
The cutterhead of a full-face rock tunnel boring machine (TBM) is constantly subjected to varying impact and dynamic loads during tunneling processes, resulting in relatively large vibrations that could easily lead to fatigue cracking of the entire machine and affect the tunneling performance and effi...
This paper presents advanced computer simulation of rock cutting process typical for excavation works in civil engineering. Theoretical formulation of the
