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,对基坑复合土钉支护结构进行较为全面的分析与测试,拟进一步揭示基坑复合土钉支护全过程的内力与变形特征,并给出了设计建议、注意事项及进一步的研究工作.试图为复合土钉支护技术在国内更广泛的应用提供较为科学的依据.
Starting from the background of specific engineering, the comprehensive analysis and testing is carried out for excavation composite soil nailing supporting structure by the establishment of finite element model, numerical calculation and comparative analysis for calculating results. The internal forces and the deformation characteristics in the whole process of excavating and supporting of excavation are further revealed, which can provide a better scientific basis for the wider application of this supporting technology at home and abroad. At last, suggestions and watchful items in design are mentioned to further the research work concerning this problem.
