基于破坏准则差异的波纹板挡墙应用分析
|
摘要
文中基于指定工程,应用有限元分析软件,首先采用摩尔-库伦准则(M-C准则)对波纹钢板拉筋带挡土墙,在分层回填下的波纹钢板变形特征进行了分析;然后用等面积圆DruckerPrager准则(D-P准则)进行分析,并与M-C准则下的挡土墙最终变形进行对比。结果表明,波纹钢板挡土墙呈现出C型的变形特征,采用D-P准则下的波纹板变形较M-C准则的波纹板变形大。
Based on the specified engineering,the finite element analysis software is applied. Firstly,the Mohr-Coulomb( MC) criterion is used to analyze the deformation characteristics of the corrugated steel sheet of the corrugated steel plate with retaining wall under layered backfilling. Then the equal area circle D-P criterion is used to analyzes the deformation characteristics of the retaining wall of the corrugated steel plate with lacing strip.Then the final deformation of the retaining wall under the MC criterion and D-P criterion is compared. The results show that the corrugated steel retaining wall exhibits C-shaped deformation characteristics,and the corrugated plate deformation using D-P criterion is larger than that of the M-C criterion.
