摘要
本文通过对在用钻机井架的现场实际测试,建立数据库、测评模型,对实测的数据用计算机技术进行分析,提出了初始弯曲应力;数据正态分布检验——x～2检验;建立回归方程;在给定置信度下测评当前承载能力的技术概念。解决了在用钻机A型井架的安全性评估问题,是一种较为合理、可靠、科学的测评技术和方法。
Through testing field derrick, setting up data base and determination model and analysing the test- ed data with computer, the technique concepts of initial bend stress, data normal distribution examina- tion(by x^2), establishing regression equation and determining present bearing capacity at the given con- fidence level are proposed out to slove the safety evaluation problem with working derrick A, which is reasonable and reliable determination technique.
