Projects handled :
1. Tsuen Wan Drainage Tunnel, Hong Kong
Activities Performed/ Detailed Task Assigned :
Finite Element modelling and SCL temporary support design for 5km, 6.5m ID drainage tunnel, inlet caverns and access adits in mixed ground conditions. Numerical analysis of tunnels at critical stretches based on rock cover, identifying the critical parameters for design, identifying the zones of potential failures, planning excavation sequences and providing numerical modelling inputs for design of tunnel linings.

Activities Performed :
Analysis of wall sections along highway alignment for different retained heights & options. Identifying geotechnical design parameters, methodology, risks and construction considerations. Preparing summary reports to assign geotechnical design parameters, forces & movements in wall sections along with preparation of risk register.

7. Liverpool Street Powerlink- Crossrail project
Activities Performed :
Geotechnical interpretation and Finite Element (FE) modelling of primary and secondary SCL support for the independent Category III design check on a new SCL cable tunnel and shaft linking into existing underground infrastructure at Liverpool Street Station. Numerical modelling was carried out using the Plaxis software to model the excavation and installation of SCL support in several stages and to assess the forces and moments exerted on primary and secondary support.
Analysis included consideration of the transmission of loading onto the sprayed lining against early-age strength gain of the SCL as well as modelling of permanent SCL support under long-term loading. Sprayed concrete linings for the shaft and tunnel are to be formed using steel fibre reinforced concrete.
