Influence of Tunneling in Cohesionless Soil for Different Tunnel Geometry and Volume Loss under Greenfield Condition

<div>Influence zones for large tunnel (<i>D</i> = 9m). B1 and B2 are top and bottom width of influence zone measured in terms of tunnel radius <i>“R</i>.” <i>“H</i>” is the height of influence zones in terms of tunnel diameter “<i>D</i>.”</div>
