摘　　要：为了提高杆塔基础智能建造水平,文章提出一种新型装配式螺旋锚基础,并研究该基础在设计荷载下的受力性能。通过有限元分析软件ABAQUS,分别建立新型装配式螺旋锚基础和普通现浇螺旋锚基础的精细化有限元分析模型,分析上拔组合工况和下压组合工况下的受力情况。研究结果表明:较普通现浇螺旋锚基础,新型装配式螺旋锚基础在设计工况下的混凝土钢筋用量显著下降,承载力接近。本文研究成果可为装配式螺旋锚基础在实际工程中的应用提供一定的借鉴与参考。In order to enhance the intelligent construction level of tower foundation,a new prefabricated heircal anchor foundation is put forward,and the load-bearing performance of a new type of prefabricated helical anchor foundation under design loads is studied,A finite element analysis models of both the new prefabricated helical anchor foundation and the conventional cast-in-place helical anchor plate foundation are established using ABAQUS software.The research findings indicate that compared to the conventional cast-in-place helical anchor plate foundation,the new prefabricated helical anchor foundation significantly reduces the amount of concrete and steel reinforcement required while maintaining a similar load-bearing capacity under desi gn conditions.The results of this study can provide valuable guidance and reference for the practical application of prefabricated helical anchor foundations in engineering projects.
