| 摘 要： | 通过建立三维有限元模型,对土钉支护的变形和受力性能进行分析,得出土钉力的合理分布。在此基础上,考虑土钉支护的水平位移,采用复合形算法,对土钉支护的结构优化设计进行研究,建立了土钉支护结构的优化设计数学模型,并编制了相应的计算程序。通过算例分析,并与基于极限平衡分析的优化结果相比较,得出合理的土钉支护结构设计的参考结论。

| Abstract: | A three-dimensional finite element model was developed to analyze the strain-stress and the deformation performances of soil nailing, and the reasonable distribution of soil-nail stress was presented. Based on these, using complex algorithms, optimal design of soil nailed structure was studied considering horizontal soil displacement. The mathematical model for optimal design of structure was established and the calculation program was compiled. By analyzing an example and comparing with the optimal results based on the ultimate balance analysis, the reasonable results of optimal design of soil nailed structure were obtained. |
