چکیده

In this paper the response of water pipelines against earthquake and seismic hazards are studied. As pipeline passes from wide areas, it may be affected by many seismic hazards. These hazards are such as ground rupture, fault movement, landslides and large deformation due to liquefaction. Based on the past experiences, damages to the water pipeline are classified and illustrated. This classification is based on the damages of the pipe body, joints , facilities and serviceability. Since the buried pipes are placed in loose grounds, their seismic response characteristics are different from buildings or buried foundations. Effective factors of seismic behaviors of buried pipes are ground characteristic, earthquake characteristic and pipe structure condition. The response of pipes during earthquake u relation between damage and ground response such as nonuniform settlements and liquefaction are classified. The methods of settlement calculation and analytical models of pipe response are also discussed. At the end , the latest results obtained from past earthquakes are classified.

اطلاعات بیشتر در مورد COI

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.
