【摘要】 根据概率理论,将作用于钻井井壁上的荷载分类模化。通过对实测荷载值的统计分析,再经荷载效应组合,确定了钻井井壁荷载标准值及其分布函数,这为钻井井壁设计向概率极限状态设计法过渡提供了重要参数。更多还原

【Abstract】 According to probabilistic theory, load on drilling shaft lining is respectively modelized. By statistical analysis on practical measuring data and organization of load effect, the normal load value and its distributive function are defined, which will provide important reference to the transition from drilling shaft lining design to probabilistic limit state design.更多还原
