Mitigating Measures for Underground Construction in Soft Ground
This general report reviews and summarieses 15 papers submitted to the session on Mitigating measures. An asset management system for underground structures is introduced to help ingrastructure owners or clients make decisions about contruction and repair. The significance of reducing tunneling- or excavation-indeced displacement and instability withing soft ground is described. LOKASI: Ruang…
Settlement Behaviour of a Shield Tunnel Constructed in Subsiding Reclaimed Area
This paper focuses on a large settlement behaviour of a shield tunnel, which is constructed in soft alluvial clay strata beneath fresh reclaimed land. The total settlement of the tunnel is more than 0.73 metres and the deformation takes place over more than twenty years after the completion of the tunnel construction. Three dimensional finite element analyses have been carried out to estimate a…
Cost Reduction of Diaphragm Wall Excavation Using Air Foam
A novel stabilizing liquid using air foam rather thenbentonite clay slurry, i.e. air foam suspension, is employed in order to stabilize the trench wall suface during a diaphragm wall excavation. Air foam suspension is used to reduce the construction costs of working on an underground diaphragm wall. Airfoam suspension is created by mixing the excavated soil with air foam made from a suface-acti…
