Пример проектирования: поддержание уровня насыпи

A roadway embankment is planned across uneven ground, requiring a height of 3 meters above the current surface with a gradual slope.

To begin, set up a leveling instrument near a benchmark with a known elevation and record the backsight reading to establish the instrument's height.

Then, move the leveling staff to the next point along the embankment and record the foresight reading to measure the change in elevation from the starting point.

Take foresight readings on a leveling staff at each point to determine existing ground elevations.

Calculate the required fill material at each point by subtracting the ground elevation from the target embankment height.

When moving the instrument to continue measurements, use the last calculated point as a temporary benchmark to re-establish the instrument’s height. Repeat the process along the embankment.

At the endpoint, confirm that the elevation aligns with the intended height specified by the design’s slope requirements.

This method ensures a uniform slope across the embankment, which helps improve stability and prevent water drainage issues.
