Test Results

Various relief grooves, located in the shafts between the liners and the hubs, were investigated with regard to their effects on the fatigue strengths of conventional tailshaft assemblies. It was found that tailshaft assemblies could be designed which would fail in the groove, regardless of whether single or increment loads were used, and that the fatigue strength of these grooved assemblies was higher than the fatigue strength of comparable ungrooved tailshaft assemblies. The grooved assemblies which had the highest fatigue strengths failed predominantly under the fitted members. The notch fatigue factors obtained with these test results were considerably higher than the estimated combined fatigue notch factors, and it is speculated that this apparent intensification is due to the added notch effect from the fitted members.

Casualty Assessment

The subway station is easy to be attacked by terrorist bombings, and it will cause heavy casualties. In this paper, a comprehensive casualty assessment method for personnel in the subway structure was established based on the existing personnel injury model. The spatial distribution characteristics of the shock wave suffered by the personnel in the subway platform were obtained. Combined with the comprehensive casualty assessment method, the personnel casualty area for the explosions in the subway platform was divided. The results show that for the same explosive charge, the maximum positive phase impulse generated by the explosion at the edge of the platform is smallest. The “notch effect” for the stair exit will increase the shock wave load. When the explosive is exploded in the center of the platform, the smaller the explosive charge is, the more obvious the “notch effect” is. When the explosive charge reaches 40 kg, the personnel safety area is reduced to a certain extent behind the stair except for the explosion happening at the stair. Also, the higher the shield door is, the larger the safety area behind the stair is.
