摘　　要：为探究预应力混凝土管桩施工对周围环境的影响,以福州市长乐区某建筑工程为背景,在考虑场地土类型影响的基础上进行预应力混凝土管桩施工振动监测,并通过竖向抗压静载试验分析预应力混凝土管桩承载力是否满足设计要求。结果表明,预应力混凝土管桩施工对周围环境的影响与场地土类型有关,中硬土上管桩施工对周围环境的影响最大,中软土次之,软弱土最小;所选试验桩的Q-s曲线均为缓变型曲线,且试验结果均满足设计要求。In order to investigate the impact of prestressed concrete pipe pile construction on the surrounding environment,a vibration monitoring study was conducted during a construction project in Changle District of Fuzhou City.The analysis considered the influence of site soil type and assessed whether the bearing capacity of prestressed concrete pipe piles met design requirements through vertical compressive static load testing.The findings indicate that the environmental effects of prestressed concrete pipe pile construction are dependent on the soil type at the site,with medium hard soil exhibiting the greatest impact,followed by medium soft soil,and soft soil having minimal influence.All selected test piles displayed slow Q-s curves,confirming compliance with design specifications.
