Rise and fall method in levelling ppt
Rise and fall method in levelling ppt-If an intermediate sight or foresight is larger than the immediately preceding staff reading then the difference between the two readings is place in the fall column A rise is added to the preceding reduced level (RL) and a fall is subtracted from the preceding RLRise and fall method is applied to resolve the levelling to detect the variation in elevation and elevation of points By resolving this table, it is possible to work out the reduced level of each point captured at staff rod with leveling machine

Use either the Rise and Fall method or the Height of Plane of Collimation (HPC) method to reduce the data Use arithmetic checks to support your answer Station Point BS IS FS Rise Fall or HPC RL CH 1 TBM 0771 1,2 A 0802 1552 0 2 B 2311 5 2,3 C9/7/ · Similarly, \sum Rise ~ \sum Fall = 494 – 468 = 026 While all the values are equal the calculated RL's are correct Leveling deals with the elevation of the earth's surface In order to construct a successful structure, the engineer must know the site parametersThe decrease level of each point is then acquired by adding the rise to or subtracting the fall from the RL of the preceding point The arithmetic check in this method is as follows ∑ BS ∑ FS = ∑ Rise ∑ Fall = Last RL First RL It can be noted that the first method of collimation is simpler and faster than the rise and fall method
