复合钢管强度设计准则

STUDY ON STRENGTH DESIGN CONCEPT OF CLAD PIPE

采用“混合原则”（ｌａｗｏｆｍｉｘｔｕｒｅ）分析复合钢管中内层防腐材料对复合钢管强度的影响，提出新的复合钢管强度设计准则，并采用蒙特卡罗方法证明了其在管线强度设计中应用的可靠性．

The effect of clad metals on the strength of clad pipes has been analyzed using the law of mixture. Based upon the above-mentioned analysis, a new strength concept was suggested for the design of clad pipes. The reliability of the new concept in the design of clad line pipes was verified by the Monte-Carlo method.
