A study on the optimum cross section design for single track double bored tunnels in high speed railway
Abstract: This paper describes determination of tunnel cross section that considers the aerodynamic problems and the railway requirements at very long tunnel such as subsea tunnel (single track double bored tunnels, train sealing 18, train velocity 350 km/hr, tunnel length 50km). As a result, the required cross-section areas with or without the pressure reduction damper are 39 m and 47 m from an air...

A study on the segmental lining design for bored tunnel in high water pressure condition
Abstract: This paper describes the concepts of design at high water pressure and impermeable ground condition in shield tunnel lining though the comparison with various design methods (elastic equation, closed form solutions, beam-spring model. Consequently, the appropriateness of various design methods depend on the main load acting on segmental lining. So, there are important of the appropriate...

Evaluation of settlement behaviour during EPB shield TBM tunneling in soft ground
Abstract: This paper presents a detailed evaluation of airport runway settlement behavior during construction of passenger terminal connecting railway twin tunnels (1,150 m long) by 7.9 m diameter EPB shield TBM in soft ground. The instrumented settlement data are analyzed to evaluate the surface settlement trough occurred by TBM tunneling. The maximum settlement is controlled within about 25 mm at the...

TBM selection methodology using the AHP (Analytic Hierarchy Process) Method
Abstract: In this study, TBM selection methods to meet soil and site conditions were presented. Factors and excavation equipment affecting TBM selection by soil and environmental condition were selected and classified. Weights between equipment and influencing factors selected were calculated by applying the AHP method. The results of the analysis influence factors, Ground condition was a major factor in...
