GEOLOGIC DATA METHODS: TUNNELS

profileWNQ

1.  GIVEN: TOPOGRAPHIC MAP WITH TUNNEL ALIGNMENT

 - ADJUSTMENTS MADE IN TUNNEL ALIGNMENT

 - INCREASE  HEAD DIFFERENCE 

 - CONTOUR INTERVAL: 10 FT

 - HORIZONTAL SCALE: 1 IN. = 80 FT: 40 SCALE x 2

 - NORTHWEST PORTAL ELEVATION IN ROCKY PEN RUN:_180 FT

 - DOWNSTREAM PORTAL ELEVATION:  160 FT_  

 

  2.  TUNNEL LENGTH: 5600 FT 

3.  CONSTRUCT THE TOPOGRAPHIC PROFILE OVER AND ALONG THE TUNNEL ALIGNMENT

- VERTICAL SCALE: 1 IN. = 200 FT

 - VERTICAL EXAGGERATION:  VE = ______

- SHOW: 

  - GROUND SURFACE

 - TUNNEL PROFILE

 - LABLE DIAGRAM

- USE ENGINEERING PAPER

  4.  PLOT GEOLOGIC STRUCTURES ON TOPOGRAPHIC PROFILE
