摘要: 全文分两部分:第一部分简述小型碟簧桩帽用于小直径钢管桩沉桩的模拟试验,第二部分详述大型预应力双向组合式碟簧桩帽应用于大直径预应力钢筋混凝土管桩沉桩的现场试验。根据试验结果,将老式替打与碟簧桩帽的应用效果进行了分析对比,证明碟簧桩帽是高效率的沉桩辅助设备。Abstract: Development of a new type Disc-Spring Cap and results of a model driving test of Small steeltubular pile are introduced.Results of a prototype driving test of reinforced concrete tubular pile withnew complex cap are given. Behaviors of the old and new type cap are compared.
