摘　　要：螺杆桩是一种造价低、承载力高、环保性好的新型桩,其桩身上部为直杆,下部为螺丝型的组合式桩基,在工程中越来越受青睐,特别是对环保要求比较严格的地区。但是螺杆桩在承载力机理、沉降理论以及在地震作用下的研究仍处于初始状态,影响了实际工程的发展和应用。基于目前国内外对螺杆桩这种新型桩基的研究现状,通过有限元分析和与安阳市某工程资料进行比较,针对螺杆桩在某种土体环境中进行荷载沉降方面的研究,为以后的理论研究和工程设计奠定一定的基础。As a new type of pile with low cost,high bearing capacity and good environmental protection,screw pile has been used as a straight bar,and the lower part is a screw type composite pile foundation,and more and more of the project has begun to use,especially for the areas with strict environmental protection requirements.However,the mechanism of bearing capacity,the theory of Settlement and the research under earthquake action of screw pile are still in the initial development state,which has influenced the development and application of practical engineering.Based on the current research situation of the new pile foundation of screw pile,based on the finite element analysis and comparison with an Anyang project,this paper studies the load subsidence of the screw pile in certain soil environment.
