Annotatsiya























Maqolada grunt to‘g‘onlarining (tekis deformatsiya sharoitida) kuchlanish-deformatsiya holati va dinamik xatti-harakatini baholash muammosining hozirgi holati batafsil tahlil qilingan. Bunda konstruktiv xususiyatlarning notekisligi hamda gruntning viskoelastik xossalari hisobga olingan.

Grunt to‘g‘onlarining dinamik holatini baholash uchun mumkin bo‘lgan siljishlar prinsipi va D’Alamber prinsipi uyg‘unligiga asoslangan matematik model ishlab chiqilgan. Modelda gruntning viskoelastik xatti-harakati Boltsman–Volterra irsiylik nazariyasi asosida tavsiflangan. Masala kompleks arifmetikaga asoslangan chekli elementlar usuli yordamida yechilgan.

Tadqiqot obyekti sifatida balandligi 195 m bo‘lgan Pskem grunt to‘g‘onining turli rezonans tebranish rejimlaridagi barqarorlashgan majburiy tebranishlari ko‘rib chiqilgan. Aniqlanishicha, to‘g‘on tanasidagi kuchlanishlarning maksimal amplitudalari nafaqat birinchi rezonans chastotasida, balki yuqori chastotalarning zich spektri sohasida ham yuzaga keladi. Kulon–Mor mustahkamlik nazariyasi asosida inshootning mustahkamligi baholanib, to‘g‘on tanasining turli qismlari uchun mustahkamlik zaxirasi koeffitsiyentlari hisoblangan hamda tashqi ta’sir chastotalari rezonansga yaqin bo‘lganda eng xavfli uchastkalar aniqlangan.
