Figure 12: Maximum pressure with distance for soil (A) and (B) along path (2). From Fig. 11a-b and 12, it can be seen that in case of soil B the maximum pressure reached the tunnel is reduced by 58.9%. Fig. 13.a-b show displacement with time at the four different locations for soil A and B respectively while Fig. 14 shows the maximum displacement along path 2 for both soils.
