摘 要: | 针对在用Π型井架存在基础沉陷这一客观现实,提出了井架结构可靠性分析的Monte-Carlo有限元法,并以ZJ-15钻机Π型井架为例进行了计算,结果表明:基础左右不均匀沉陷对构件可靠性指标的影响较大,而基础前后不均匀沉陷的影响相对较小。

Abstract: | In the light of the foundation sinkage of Π-type masts occurred in the field, the authors put forward the Monte-Carlo finite element method for analyzing the structural reliability of the mast, and,as an example, conduct an investigation in the ZJ-15 rig mast. It indicates that the left-right unequal sinkage of the foundation exerts considerable influence on the reliability of the mast members, while the influence caused by front-back unequal sinkage is relatively minor. |
