ارزیابی روابط ریاضی سرعت موج برشی و نتایج آزمون نفوذ استاندارد با رویکرد آمار بیزین

سولماز چاروسايي, نويد خياط, مهدي مهدوي عادلي

چکیده


سرعت موج برشی به‌عنوان یکی از مهم‌ترین پارامترهای ژئوفیزیکی می‌باشد که پاسخ لرزه‌ای سایت‌ها در قالب آن بیان می‌شود. این پارامتر لرزه‌ای اطلاعات ارزشمندی راجع به ساختگاه پروژه را می‌دهد اما ازآنجایی‌که آزمایش‌های ژئوفیزیکی معمولاً گران و زمان‌بر هستند استفاده از روش‌های غیر مستقیم به‌منظور کاهش هزینه‌ها رو به افزایش است. تحقیقات زیادی دراین‌باره در مناطق مختلف جهان انجام شده است که در اکثریت آنها از دو معادله توانی ساده و توانی چندگانه جهت استخراج معادلات استفاده کرده‌اند. اما این تحقیق با استفاده از توابع جدید تعریف شده توسط آمار بیزین نشان داده است که معادلاتی با اعتباری به‌مراتب بیشتر از روابط موجود در سوابق تحقیق می‌توانند جهت تخمین سرعت موج برشی به‌کار گرفته شوند.


موضوع


سرعت موج برشی، آزمون نفوذ استاندارد، همبستگی آماری، آمار بیزین.
