Аннотация

Gidrotexnika inshootlari deformatsiyasini kuzatishda qo'llanilayotgan sun'iy yo'ldosh navigatsiya tizimlari (GNSS) va radiolokatsion interferometriya (InSAR) usullarining har biri o'ziga xos fazoviy va vaqtiy cheklovlarga ega: GNSS uzluksiz, ammo nuqtaviy ma'lumot beradi; InSAR keng hududni retrospektiv qamrab oladi, biroq deformatsiyani faqat yo'ldoshning ko'rish chizig'i (LOS) bo'yicha bir o'lchamli proyeksiyada qayd etadi. Mazkur maqolada ikki usulni yagona metodologik doirada birlashtirishning uch bosqichli sxemasi — fazoviy moslashtirish, GNSS siljish vektorini ko'rish chizig'iga proyeksiyalash va qoldiq deformatsiyani baholash — asoslab berilgan hamda u To'polon tuproqli to'g'oni (Surxondaryo viloyati) misolida sinovdan o'tkazilgan. To'g'onda 2024-yildan buyon ishlab turgan o'nta stansiyali ko'p tizimli GNSS tarmog'i gorizontal bo'yicha ±2 mm, vertikal bo'yicha ±4 mm aniqlikni ta'minlaydi; Sentinel-1 ma'lumotlari asosida 2020–2024-yillar uchun bajarilgan PS-InSAR (6 233 nuqta) va SBAS (18 391 nuqta) tahlillari esa to'g'on va suv ombori hududini to'liq qamrab olgan. Ikkala texnologiya ham deformatsiyaning quyi b'ef tomon yo'nalganligini bir-biridan mustaqil ravishda tasdiqlaydi: GNSS bo'yicha gorizontal siljish azimuti 170–190°, InSAR bo'yicha esa maksimal cho'kish aynan quyi b'ef zonasida qayd etilgan. Shu bilan birga, ikki usul to'g'onning turli qismlarini qamrab olishi aniqlandi — GNSS asosan toj zonasini, InSAR esa bermalar va yuklanmagan qiyalikni. Bu holat ularning o'zaro almashinuvchi emas, balki o'zaro to'ldiruvchi ekanligini ko'rsatadi va kompleks monitoring tizimini shakllantirish zaruratini asoslaydi.
