摘要
采用三维非线性有限元方法,以等效塑性应变(PEEQ)指标作为材料是否进入塑性状态的评价指标,对某工程升船机排架柱基础中的粉砂质泥岩刻槽置换效果进行了分析研究,并详细分析探讨了设置平硐以及采用贴坡混凝土两种情况对刻槽置换效果的影响。
The three-dimensional nonlinear finite element method is used to study the effects of replacing the silty mudstone with concrete in the bent column foundation of a shiplift engineering, in which the equivalent plastic strain （PEEQ） is taken as the indicator to evaluate material＇s plastic state. The influences of adding an adit or adopting fitting slope concrete on concrete replacement are also analyzed herein.
