By establishing the finite element model of the K type derrick ,the distribution of stress and deform-ation displacement of derrick under the effect of designed loads were analyzed ,and the dangerous stress areas of derrick during loading process were determined .Based on the results of finite element analysis ,the optimi-zation of strain gauge selection and the layout of measuring points in derrick detection scheme were carried according to the requirements of standard SY/T6326 -2008 ,which can serve as a reference for the inspec-tion and safety evaluation of the derrick .
