Suv ombori to‘g‘onlarida siljish deformatsiyasi, ularning barqarorligi va xavfsizligiga ta‘sir qiluvchi omil hisoblanadi. Ushbu maqolada siljish deformatsiyasining mexanizmlari, uni vujudga keltiriladigan omillar va ushbu deformatsiyalarnikuzatish va tahlil qilish metodologiyalari o‘rganiladi. Siljish deformatsiyasini tushunib,muhandislar to‘g‘on nosozliklari bilan bog‘liq xavflarni kamaytirish uchun samaraligeodezik kuzatuv va texnik strategiyalarni amalga oshirishlari mumkin.

Shear deformation in reservoirdams is a factor affecting their stability andsafety. This article examines the mechanisms ofshear deformation, the factors that cause it, andthe methodologies for observing and analyzingthese deformations. By understanding sheardeformation, engineers can implement effectivegeodetic monitoring and engineering strategies toreduce the risks associated with dam failures.

Сдвиговые деформации вплотинах водохранилищ являются фактором,влияющим на их устойчивость и безопасность.В данной статье рассматриваются механизмысдвиговой деформации, факторы, ее вызывающие,а также методологии наблюдения и анализаэтих деформаций. Понимая деформацию сдвига,инженеры могут реализовать эффективныйгеодезический мониторинг и инженерныестратегии для снижения рисков, связанных спрорывами плотин.
