摘要
目前,国内外对损伤井架承载能力的研究局限于宏观损伤。通过等效处理坑蚀引起的应力集中损伤,借助有限元软件ANSYS计算含有应力集中损伤井架的承载能力。与现场测试评定的结果比较,数值相差1%,证明ANSYS软件的计算精度可以满足应力集中损伤井架的承载能力评定需要。
presently,the study on bearing capacity of damaged derrick structure was defined to macroscopic injure.Through equivalently disposing stress construction caused by pit corrosion,aiding by finite software ANSYS,the bearing capacity of stress concentration derrick is calculated.Comparing the results tested on field,number difference was within 1%,proving that the calculated precision of software ANSYS can meet the requirement of carrying capacity assessment of stress construction derrick structure.
