2025 2533 1.4-rasm Yuzani nivelirlash jurnali 2990 Kuyidagi formula orkali asbob gorizonti xisoblab topiladi: AG = N Rp + a
bu yerda: N Rp –reper uchun kabul kilingan nuktaning shartli balandligi; a – shu nuktaga o’rnatilgan reykaning qora tomonidan olingan sanok. Misolimizda: N RP = 515,404 m; a = 2584 mm; AG = 515,404 + 2.584 = 517,988 m. Kuyidagi formula yordamida kvadrat uchlari balandliklari xisoblab chikariladi.

N i =AG – v
i ; bu yerda: N i – aniqlanishi kerak bo’lgan kvadrat uchining balandligi; v i – shu
nuktaga o’rnatilgan reykadan olingan sanok. Misolimizda: Na 2 = 517,988 – 1.987 = 516,001 Na 3 = 517,988 – 0.545 = 517,443 Na 4 = 517,988 – 0.118 = 517,870 Nb 1 = 517,988 – 2.493 = 515,495 Nb 2 = 517,988 – 1.326 = 516.662 Nb 3 = 517,988 – 0.156 = 516.832 Nb 4 = 517,988 – 0.681 = 517.307 Nv 1 = 517,988 – 2.334 = 515.654 Nv 2 = 517,988 – 1.382 = 516.606 Nv 3 = 517,988 – 1.290 = 516.698 Nv 4 = 517,988 – 2.025 = 515.963 Ng 2 = 517,988 – 2.047 = 515.941 Ng 3 = 517,988 – 2.162 = 515.826 Ng 4 = 517,988 – 2.533 = 515.455 Nd 3 = 517,988 – 2.782 = 515.206 Nd 4 = 517,988 – 2.990 = 514.998 Xisoblangan balandliklar tegishli kvadrat uchlari yoniga reykadan olingan sanoklar ostiga yozib chikiladi.(1.2-rasm)
