摘　　要：随着经济以及社会的不断发展,现阶段建筑工程发展愈加快速,已经逐渐成为我国国民经济的重要支柱之一,工程中施工技术的重要性也逐渐凸显出来。通过对复杂地质条件下高强度预应力管桩静压施工过程中出现的具体问题进行分析研究,解决了在复杂地质条件下高强度预应力管桩静压施工的技术难题,并结合实际工程案例总结了施工经验,值得推广和借鉴。With the development of economy and society, the construction engineering is developing more and more rapidly, which has gradually become one of the important pillars of our national economy, and the importance of construction technology is also gradually prominent. In this paper, through the analysis and study of the concrete problems in the static pressure construction of high strength prestressed pipe pile under complex geological conditions, the technical problems of static pressure construction of high strength prestressed pipe pile under complex geological conditions are solved. Combined with practical engineering cases, the construction experience is summarized, which is worth popularizing and drawing lessons from.
