Profile Cross-Section

Practical Surveying
Profile Cross-Section
1- Report number ,, 6,,,
2-Report name
Profile and cross –section leveling.
Procedure of profile:
1 - Specify the direction of the longitudinal section
(path section) by selecting the location of the station, which should be equal in distances (15, 20, 25, and 50) m according the nature of the earth's surface.
2 - Start leveling process by leveling the •stations from known Bench mark and this process is closed in order to confirm the accuracy of the survey process.
Cross-Sections
•Sections at right angles to the centerline of a proposed or
existing project such as a road
•Scale 1/50 or 1/100 for both horizontal and vertical axes.
APPARATUS
1-Level instrument
2-tripod
3-staff
4-tape
5-pin
6-range pole
OBJECT
Longitudinal leveling is an operation of doing a
leveling job to determine .
The profile of a ground surface along a given line
this is generally the center line of purposed
Alignment .such as
Highway , railway ,pipeline , and sewerage
CROSS- SECTION
Of the project station for calculation (cut and fill )
Area –volume of earth.
CALCULATION
1-Grade A = Ground A
2-Grade B= grade (A) + Slope × Distance(A & B)
3-Grade C=grade(A) + Slope × Distance (A & C)
