CONTOH PERHITUNGAN DATA DALAM ILMU UKUR TANAH


v RUMUS-RUMUS YANG DIGUNAKAN
  1. Perhitungan jarak optis pada profil memanjang

( D = BA – BB ) x 100

dimana : D = Jarak Optis

BA = Benang Atas

BB = Benang Bawah

  1. Perhitungan Jarak Optis Pada Profil Melintang

( D = BA – BT ) x 100

dimana : BT = Benang Tengah

  1. Perhitungan Beda Tinggi Pergi dan Pulang

( AH = BT belakang – BT muka )

  1. Perhitungan Beda Tinggi Rata-Rata

AH Rata-rata = ( AH pergi + AH pulang ) / 2

  1. Perhitungan Beda Tinggi Untuk Profil Melintang (Detail)

AH = BT belakang – BT detail

  1. Perhitungan Tinggi patok Utama

TPU = Tinggi titik + AH rata-rata

  1. Perhitungan Kemiringan Detail = AH detail x 100 % / Jarak ukur detail
  2. Perhitungan Tinggi Titik Detail

TTD = TPU + AH detail

  1. Perhitungan Kemiringan Patok Utama

AH rata-rata x 100 % / Jarak ukur detail

  1. Perhitungan Volume Timbunan

D = ( BA – BB ) x 100

ü Persegi panjang = Panjang x Lebar

ü Segitiga = ½ Alas x Tinggi

ü Volume Perhitungan timbunan dan galian = ½ x Jarak muka + ½ x Jarak belakang

ü Trapezium = Jumlah dua sisi berhadapan x Tinggi
