BCA has worked together with the British Geological Survey (BGS) to establish a new stratigraphical framework which involved renaming of the geological units to replace DSTA (2009) used in the publication.
It is the time to have an in-depth understanding on the new geological units and its application in engineering works. At the same time, understanding the spatial distributions of soil and/or rock profiles is vital to underground geotechnical design.
3D geological models have became efficient and effective way of storing, processing, presenting, and analysing geological data, as well as vital research direction in geological fields, such as engineering geology.
A large TBM has been used in the Cross Island Line project of the LTA. Complex tunnelling works are likely to pose a higher risk to nearby buildings, especially if they are performed in difficult ground conditions. As part of the Risk Based Framework for Large Diameter TBM, some key measures are highlighted in this presentation that aim to mitigate such tunnelling risks during
the upcoming large diameter tunnelling projects.
In addition to the above, prestigious speakers will present case studies on tunnelling, deep excavation, pipe jacking projects and share the geotechnical challenges encountered during the constructions as well as the appropriate mitigation measures.
