Design and Welding Construction of Edge Plates at the Bottom of a Big Oiltank;

The welding construction was one of important link in long distance pipeline construction.

In view of Russia "East Siberia-Pacific" oil pipeline project realistic situation,and considering construction experience and lessons of the china petroleum pipeline bureau in recent years,this article has elaborated the problem exhaustive that should be concerned in welding construction.

While most of researches on adjacent construction are based on experience and case study with little system study,it seems from actual design norms of China that such reaches are mainly based on no-sphere of influence of elastic solution and empirical value,or separate model,which lack of require and sufficiency analysis by theory.
