摘　　要：以实测应变参数为主的静态应变测试法是目前对现役井架可靠性评估的主要方法。在该方法中引入计算机仿真技术,分析井架的应力分布规律。通过对井架模型的静力分析,找到井架结构中应力较大的杆件,从而确定合理的应力测试点的布置位置和测试点的个数,为井架检测中测试点的优化布置提供科学依据。Static strain testing method which tests mainly strain parameter is a main method of the derrick dependability assessment at present. The method used the computer simulation technology to analyse the law of stress distribution of derrick. Through analysing static stress of the derrick model, found a pole with the biggest stress in the structure of the derrick. As a result, the position and amount of stress testing point were determined. The application of the technology offers the scientific basis for testing point position distribution during derrick testing.
