On a vertical shaft a bearing will undergo axial motion when there is a change in radial clearance. This can be shown (fig. 3) by first considering a warm bearing (shown in red). Both rings are at the same temperature, and there is a small bearing clearance. The bearing is supported on the outer ring. The inner ring is slightly displaced downward.

collapse of shaft walls. The need for a robust and accurate surveying and inspection tool is very clear. The concept of the Vertical Opening Inspection System (VOIS) is very simple, and developed naturally from early crude attempts at shaft inspection which essentially involved deploying cameras into vertical shafts via winch.

The net section size of the shaft above Metro Line 11 is 15.5 m × 5.5 m, and the shaft depth is 6.3–11.6 m, as shown in Table 3. The depth of foundation pit in ramp area is 9.2–11.6 m, and two temporary supports of 30 cm thick grid spraying are set in the middle. Fig. 4. Layout plan of shaft above Metro Line 5.

In each case, the area of each shaft was the total area of shafts divided by the shaft amount. The shafts were evenly distributed in the region between the fire and the right end of the tunnel and numbered consecutively in the downstream direction of the fire (for example, the shafts in case with three shafts for natural ventilation were numbered as shaft 1, shaft 2 and shaft 3, …

Vertical leadership is organized from the top down, when tasks and responsibilities are allocated by a leader who stands at the top. Shared leadership differs from vertical one in terms of a wider degree of decision-making power delegation to the followers. Burke (2006) suggested that shared leadership is more complicated and time consuming ...
