摘　　要：预应力管桩施工工艺在基础施工中有施工速度快、单桩承载力大的优点,被越来越多的项目应用。但该施工工艺在遇到不均匀分化岩层、腐蚀性地下水等复杂地质情况下存在质量问题。本项目通过工程实践,引入预应力管桩植桩法施工技术,可有效解决复杂地质情况下常规预应力管桩施工工艺存在的问题。The construction technology of prestressed pipe piles has the advantages of fast construction speed and large bearing capacity of single piles in foundation construction, and is used in more and more projects.However, this construction process has quality problems when encountering complex geological conditions such as unevenly differentiated rock formations and corrosive groundwater. Through engineering practice, this project introduces the construction technology of prestressed pipe pile planting method, which can effectively solve the problems existing in the construction technology of conventional prestressed pipe piles under complex geological conditions.
