MIKROSEYSMIK TEBRANISHLAR ASOSIDA TERMIZ SHAHRI HUDUDIDA TARQALGAN GRUNTLARINING DINAMIK TAVSIFI VA SEYSMIK ZAIFLIGINI BAHOLASH
##submission.downloads##
Ushbu maqolada Termiz shahri hududida mikroseysmik kuzatuvlar asosida gruntlarning seysmik zaifligini baholash masalalari yoritilgan. Tadqiqotda Nakamura (HVSR) usuli yordamida gruntlarning ustun rezonans chastotasi, spektral kuchaytirish koeffitsienti hamda grunt zaifligi indeksi (Kg) hisoblandi. Olingan natijalar Geopsy va SESAME dasturlari yordamida qayta ishlanib, GAT texnologiyalari asosida Termiz shahri hududi uchun gruntlarning seysmik zaiflik indeksi xaritasi ishlab chiqildi. Tadqiqot natijalari lyossimon va suvga to‘yingan gruntlar tarqalgan hududlarda gruntlarning seysmik tasirlarga nisbatan zaifligi yuqori ekanligini ko‘rsatdi. Ishlab chiqilgan xarita seysmik rayonlashtirish, qurilish maydonlarini tanlash hamda muhandislik-geologik baholash ishlarida amaliy ahamiyatga ega.
