摘　　要：从特定的工程背景出发,通过建立有限元模型、数值计算和对比分析对基坑纯土钉支护结构进行较为全面的分析与测试,拟进一步揭示基坑纯土钉支护全过程的内力与变形特征,试图为纯土钉支护技术在国内更广泛的应用提供较为科学的依据.提出了设计建议及注意事项,并讨论了进一步的研究工作.Starting from the background of a specific engineering,a comprehensive analysis and testing are carried out for the excavation soil nailing supporting structure by establishing a finite element model,by numerical calculations and a comparative analysis.The internal forces and the deformation characteristics in the whole process of excavating and supporting are further explored,which can provide a better scientific basis for the wider application of this supporting technology at home and abroad.At last,suggestions and warnings are given,and further work concerning this problem is also discussed.
