| 摘 要： | 在船闸下闸首工程的结构计算分析中,考虑地基土体材料的非线性特性,采用非线性有限单元法,对嘉陵江新政船闸下闸首进行了计算分析研究。运用ANSYS10.0通用计算软件,建立了三维非线性弹塑性有限元模型,采用D-P准则对闸首的回填土和地基土体进行计算,经对嘉陵江新政船闸闸首在不同工况下的应力和应变分布特征进行分析比较,验证了模型的正确性和实用性。

| Abstract: | In the numerical analysis of the lower head of a ship lock,the nonlinear characteristics of foundation soil were considered.The lower head of Xinzheng ship lock in Jialing River was researched by the nonlinear finite element method.Based on the general software ANSYS10.0,a 3-D nonlinear elastoplastic finite element method model was set up.Backfill soil and foundation soil of lock head were calculated by D-P criterion. The distribution characteristics of stress and strain for the lock head of Xinzheng ship lock under different conditions were analyzed and compared in order to validate the correctness and practicability of the model. |
