Cross-Section Leveling

Cross-section leveling is usually done with a hand level after the profile run has been made. The method is as follows: From the profile run, you know the center- line elevation at each station. Suppose you want to take cross-section elevations at 10 ft intervals for 40 ft on either side of the center line.

LEVELLING APPLICATIONS 1. Longitudinal sections of ground level in road

Cross-sections are plotted mainly for roads, railways, tanks etc. with some width. (I.e. not relevant for sewers). A spacing of 10m or 20m is common between cross-sections. Once again there is a need to reproduce the ground level accurately in order to proceed with the road design (considerations of width, level etc.). The example of a road

In using the trapezoidal method, the area of any cross section is obtained by dividing the cross section into triangles and trapezoids, computing the area of each part separately and taking the total area of the verticals to the ground line (Fig. 24.5) in order to divide the cross section into two triangles and two trapezoids. Assumption is made that the ground is perfectly straight between

In cross-section leveling, you determine the elevations of points on a succession of lines running at right angles to the lengthwise line of the highway. The principal purpose of profile leveling is to provide data from which the depth of fill or cut required to bring the existing surface up to, or down to, the grade elevation required for the highway can be determined.

Explain The Procedure For Profile Levelling And Cross Sectioning

For cross Sectioning: While profile leveling is in progress, cross-sectional leveling should also be done. The cross-sections are taken perpendicular to the Centre line of the alignment at some regular intervals (say 20m, 40m etc). The purpose of cross-sectional leveling is to know the undulation of the ground surface transverse to the centre of the road.
