E-MODUL ILMU UKUR TANAH

= (1.477 - 1.521) = - 0.044 m

3. Perhitungan Beda Tinggi Rata-Rata

h 12 = h 12pos .I  h 12pos .II
2

= . 0 032  . 0 032 = + 0.032 m
2

h 23 = h 23pos .I  h 23pos .II
2
= . 0 012  . 0 012 = + 0.012 m
2

h 31 = h 32pos .I  h 32pos .II
2

=  . 0 044  ( . 0 044 ) = - 0.044 m
2

4. Perhitungan Jumlah Beda Tinggi

Ʃh = 12h + 23h + 31h = 0.032 + 0.012 +(-0.044)
= 0

5. Perhitungan Kesalahan

W = Ʃh = 0

6. Perhitungan Toleransi

 d 91 . 40
10
T = 1000 = 1000 = 0.003 m = 3 mm
1000 1000

7. Perhitungan Koreksi

w
0
Koreksi = = 0
n 3
8. Perhitungan Kontrol Kesalahan

Syarat = W  T 0  0.003

9. Perhitungan Tinggi Titik
