The following consecutive readings were taken with a level and a 4m leveling staff on a continuously sloping ground at a common interval of 30 m on line AB. Chainage 0 Level Station 30 0.585 0.930 A 60 1.95 90 2.845 120 3.645 150 3.93 B The reduced level (RL) of station A is 50.00. Calculate the reduced levels at all the points where the leveling staff is placed. Tabulate the results and apply usual checks. Also determine the gradient of line AB.

Transcribed Image Text:The following consecutive readings were taken with a level and a 4m leveling staff on a continuously sloping ground at a common interval of 30 m on line AB.
| Chainage (m) | 0 | 30 | 60 | 90 | 120 | 150 |
|--------------|------|------|------|------|------|------|
| Level | 0.585| 0.930| 1.950| 2.845| 3.645| 3.930|
| Station | A | | | | | B |
The reduced level (RL) of station A is 50.00. Calculate the reduced levels at all the points where the leveling staff is placed. Tabulate the results and apply usual checks. Also determine the gradient of line AB.
Explanation:
- A table presents the chainage increments in meters from 0 to 150, and corresponding level readings at each interval.
- Station A is at the initial chainage of 0 meters and station B at 150 meters.
- The task involves calculating reduced levels at each chainage and determining the gradient of the line.
