چکیده

وقوع گسیختگی­های ناشی از گسلش سطحی زلزله­های اخیر، ضرورت بررسی اندرکنش گسل- سازه - فونداسیون را در طراحی سازه­های مهندسی و  شریان‌های حیاتی واقع در حریم گسل،  بیش‌ازپیش می­طلبد. در این مقاله، اندرکنش گسلش سطحی حاصل از عملکرد یک گسل معکوس و مجموعه پی شامل؛ فونداسیون سطحی و ریز­شمع ها و همچنین اثر آن بر جابه‌جایی­های افقی و قائم فونداسیون، با استفاده از مدل­سازی عددی مورد بررسی قرارگرفته است. مهم‌ترین فاکتور مورد استفاده در این مطالعه، نسبت فاصله محل برخورد گسلش به زیر پی به عرض پی (S/B) می‌باشد. نتایج نشان می­دهد جابه‌جایی افقی فونداسیون به حضور و موقعیت قرارگیری ریزشمع­ها حساسیت اندکی نشان می­دهد درحالی‌که جابه‌جایی قائم و چرخش فونداسیون  با وجود ریز شمع­ها به موقعیت قرارگیری مجموعه پی نسبت به گسلش حساس بوده و وجود ریز شمع­ها همواره باعث کاهش مقادیر جابه‌جایی قائم فونداسیون می­گردد. نتایج همچنین نشان می­دهد بهترین حالت برای کنترل چرخش فونداسیون، حالت S/B
