摘　　要：针对挡土墙模板的结构特点,应用有限元方法中的板壳理论对扶壁式挡土墙模板这一复杂结构的设计及优化进行研究。在拉杆位置的优化模型上,通过位置布局优化,模板的变形量减小了39%,通过计算得到了模板最大变形量与板壳厚度的关系曲线和模板面板应力分布情况。研究结论可为类似薄壁结构的优化设计、参数计算提供参考,也说明有限元方法对提高模板设计的安全性、可靠性和经济性具有重要的应用价值。Based on the structural feature of the retaining wall template, we use plate and shell theory of finite element method （FEM） on the complex structure buttressed retaining wall template for the design and optimization of the related research. On the optimization model of the rod position, through the location layout optimization, we make the template deformation reduced 39%. Through calculation, we have drawn the tem- plate curves showing the relationship between the maximum deformation and the thickness of plate and the dis- tribution of the stress component templates panel. This paper can also provide a reference for other thin-walled structure optimization design and parameter calculation. It also shows that finite element method proves to be of great value in improving the safety, reliability and reducing cost in penal desing.
