TRAPETSIYASIMON KANALDA TUB OSTI VA MUALLAQ OQIZIQ SARFINI HISOBLASHNING ZAMONAVIY USULLARI
Referat
Ushbu maqolada trapetsiyasimon ko‘ndalang kesimga ega bo‘lgan ochiq kanalda tub osti va muallaq oqiziq sarflarini hisoblashning zamonaviy nazariy asoslari va amaliy usullari bayon etilgan. Har xil qiyalikka (m 1 ≠ m 2 ) ega bo‘lgan donador grunt asosidagi kanallar uchun Meyer- Peter va Müller (1948), Bagnold (1966), Engelund -Hansen (1967) hamda Rouse-Einstein va Van Rijn (1984) usullari qiyosiy tahlil qilingan. Manning tenglamasi asosida gidravlik hisob-kitoblar amalga oshirilgan, Shields parametri va Rouse sonining oqiziq harakatiga ta’siri o‘rganilgan. Hisoblash algoritmi dasturiy vosita yordamida sinab ko‘rilgan va b=15 m, h=5 m, m 1 =m 2 =3, i=0,0003, d=0,5 mm bo‘lgan misolda jami oqiziq sarfi 6,81×10⁻³ m³/s ekanligi aniqlangan.Kalit so'zlar
