摘　　要：以渤海湾的两座典型海洋导管架平台为研究对象，运用非线性逐步破坏分析方法，提出了在环境荷载作用下海洋导管架平台结构抗震可靠性的分析方法，并计算了相应的可靠度．计算与分析结果表明，本例的海洋导管架平台的抗震可靠度较大，即失效概率很小，而且该分析方法是一种较为简单、实用和可靠的分析方法．By means of nonlinear pushover failure analysis method, the aseismic reliability analysis of two off shore jacket platforms is studied according to its ocean location and environmental loading there. On the basis of this, an aseismic reliability analysis approach is presented. The results show that the aseismic reliability index of those platforms is high and the failure probability is very low. Also it is proved that this aseismic reliability analysis approach presented here is rather simple, practical and reliable.
