| Abstract: | With an introduction of the producing method of CSOP10 shield tunnel segment concret and C20P6 spraying concret used in Nanjing metro line, this paper holds that C50P10 segment concret,mixed with 20%-25% Grade I fly ash,shall possesse fine working capability, mechanical capability and extended durability. The same way, the stability of initial support shall be guaranteed during metro tunnel construction, when the spraying concret mixed with fly silica is adopted in the metro area without shower, and when the spraying concret mixed with qulck-setting and rapid-hardruing cement is adopted in soft soil layers. |
