Data Management System for the S1S2 Tunnels of the High -Speed 2 Link Project in
Abstract: The S1/S2 contract for the new High Speed 2 (HS2) in the United Kingdom linking London to Birmingham and later Leeds and Manchester will consist of 22 km of tunnels and is estimated to cost GBP 3.3 billion. As part of the contract, an Instrumentation & Monitoring data management system to support the construction phase (Phase 2) is provisioned. This paper discusses the development of the data...

Full scale testing of rebar and SFRC segmental lining using independent and wireless instrumentation systems
Abstract: Development and acceptance of steel fibre reinforced concrete (SFRC) segmental tunnel lining requires an accurate understanding of the performance of the SFRC segments under real load conditions. An innovative instrumentation scheme has been implemented during the construction of the Liantang Lung Shan highway tunnels in Hong Kong to evaluate the distribution of the loads in the segments during...

Probabilistic Subsurface Modelling in Tunnelling Applications: Suggestions for Use in Practice
Abstract: Tunnel projects are often dominated by spatial uncertainty in geological-geotechnical conditions. In recent years, there has been an increasing interest in the use of geostatistical or random field methods for probabilistic subsurface modelling in tunnelling applications. These methods provide the means for modelling the spatial variability and quantifying the spatial uncertainty in...

Tunnel Process Control for Klang Valley Metro Phase 2 Using Machine Learning and Artificial Intelligence
Abstract: The Klang Valley Mass Railway Transit in Kuala Lumpur is mid-way through line 2 construction. The line faces several challenges including mixed face conditions, variable ground water and geologic hazards with high potential for large settlements and sink holes. Consequently, the influences on tunnel processes such as advance rates and cutter tool wear are hard to estimate. This paper presents...
