The economic impact analysis of process parameters change of large section slurry shield in urban water-rich sandy gravel stratums
Strategic Study of CAE ›› 2010, Vol. 12 ›› Issue (12) : 108 -112.
Taking the underground diameter shield construction of Beijing railway for example, the choosing principles of process parameters in different engineering geo-conditions and changing boundary conditions were introduced. The cost difference and change were analyzed according to the analysis of construction efficiency and machine material consuming when the process parameters were adjusted.[
