Abstract
Ushbu maqolada O‘zbekiston Respublikasi sharoitida avtomobil yo‘llari temir-beton ko‘priklarining to‘sinli oraliq qurilmalari konstruktiv parametrlarini optimallashtirishning zaruriy shartlari tahliliy nuqtayi nazardan ko‘rib chiqilgan. Dastlabki masala qo‘yilishida ko‘rib chiqilgan konstruktiv sxemalar, asosiy geometrik parametrlar va ularning kuchlanish-deformatsiya holatiga ta’siri tahlil qilingan. Temir-beton konstruksiyalarni optimal loyihalash bo‘yicha klassik hisoblash yondashuvlari zamonaviy tadqiqotlar bilan qiyoslangan. Geometriya, armaturalash, mustahkamlik va ekspluatatsion yaroqlilik talablari, shuningdek iqtisodiy va uzoq muddat xizmat qilish mezonlarini birgalikda hisobga olish zarurati bilan bog‘liq ilmiy muammo aniqlashtirilgan. Keyingi sonli tadqiqot uchun O‘zbekistondagi aniq obyekt bo‘yicha hisoblash hududi va seysmik sharoit, harorat ta’sirlari, transport yuklamasi modeli, materiallar, xizmat muddati hamda konstruktiv o‘zgaruvchilar diapazonlarini belgilash zarurligi ko‘rsatilgan. Keltirilgan egilish grafigi aniq ko‘prik hisobi natijasi emas, balki shartli matematik misol ekanligi ochiq ko‘rsatilgan. Ushbu maqolada sonli optimallashtirish bajarilmaydi.
