摘　　要：岩溶地区其恶劣的地质环境对工程施工非常不利,使得施工难度较大而且工程很容易出现质量问题。桩基作为重要的结构,对于工程具有重要的作用。在岩溶地区进行桩基施工时,需要选择合适的桩基施工技术,才能保证桩基的质量。文章从岩溶地区对于工程施工的影响出发,以端溪小学建设项目工程为例,介绍了岩溶地区的桩基施工技术和质量控制细节,对岩溶地区采用预应力混凝土管桩容易出现的问题进行分析,提出了有效的处理方法及解决方案,为类似工程案例提供参考。The harsh geological environment in karst areas is very unfavorable for engineering construction,making it very dificult and prone to quality problems during construction.As an important structure,pile foundation plays an important role in engineering.In karst areas,it is crucial to choose appropriate pile foundation construction technology to ensure the quality of pile foundation construction.Starting from the impact of karst areas on engineering construction,this article takes the construction project of Duanxi Primary School as an example to introduce the pile foundation construction technology and quality control details in karst areas.It analyzes the problems that are prone to occur when using prestressed concrete pipe piles in karst areas,proposes effective treatment methods and solutions,and provides experience reference for similar engineering cases.
