Tunnel Type

3 Center Circle

Create a Tunnel composed of three circles having different center.
 
3 Center Circle + Invert

Create a Tunnel composed of three circles and Invert.
 
5 Center Circle

Create a Tunnel composed of five circles having different center. 

5 Center Circle + Invert

Dimensions

Invert

i. Tangential – User can determine both the radius and angle of invert section within general section dimension

ii. Radius – User defines the radius of invert section, and the program automatically defines the angle.

iii. Angle - User defines the angle of invert section, and the program automatically defines the radius.
 
R1, R2, R3, R4, A1, A2, A3, A4

Define dimensions of general section for specified tunnel type. Please refer to the following picture for data input of each category. (Look at the examples below.)

 

Section Type

Full

Create the section line of a Full tunnel.
Left Half

Create the section line of the Left half of a tunnel section.
Right Half

Create the section line of the Right half of a tunnel section.
 

Include Rock Bolts

Number of Rock Bolts

Enter the number of Rock Bolts.
Length of Rock Bolts

Enter the length of Rock Bolts.
Arrangement

Specify the arrangement of Rock Bolt location. User can choose between Tangential Pitch and Rotation Angle Method.
 

Location

Use Snap

Specify the coordinates of the center of a tunnel section by a mouse-click on the Work Plane. Upon clicking a point, the tunnel section line is created, centered on the point.
Section Center

Enter the center coordinates of a tunnel section.

 

Make Wire

Make the section line of the tunnel into a single wire.  If not checked on, the tunnel section line will be created with a number of edges.
