چکیده
Piles are widely used in marine constructions. Pile supported wharves and jetties, oil and gas fixed platforms and anchor piles could be named as the most common applications of piles in marine environments. Sea waves and currents impose dramatic lateral loads on the above mentioned structures. Moreover, seismic loading and wind forces are of lateral kinds with great influences on the pile supported structures. As a result determining the appropriate behavior of piles under lateral loading would be of great importance in the designing steps. Well established procedures of designing marine structures introduce soil-pile interaction methods as more accurate ways to represent better understanding of pile’s responses under lateral forces in comparison to the old methods neglecting such effects [1, 2, 3, 4, 5]. Each of the different ways of regarding soil-pile interaction greatly deals with soil properties like Young’s modulus, Poisson’s ratio, soil friction angle, soil cohesion, dilation angle etc. Among these properties Young’s modulus (E) proposed by different codes and researchers sometimes varies a lot in a way that even for a specific soil type there is no overlap. Referring to the literature it is due to the different methods selected by each researcher or scientific institute to obtain the values.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
