增量破坏型机动安定性分析方法及其应用

Numerical method of shakedown analysis based on kinematical-type theorem forincremental collapse and its applications

根据避免累积塑性变形发生的安定准则,构造了相应的安定性数值求解方法,进而用于确定海洋平台地基的安定荷载上限近似解,为评价地基在复杂变值荷载作用下的承载力提供了依据。

In this paper, based on the kinematicaltype shakedown criterion for incremental collapse, a computational procedure for avoiding incremental collapse is formulated and then is applied to determine the bearing capacity of offshore platform foundations under transient or cyclic loading.
