摘　　要：以往的竖向抗压静力载荷试验费时费力,且存在着不小的安全隐患,亟需对传统的静载反力装置进行改进。新型管桩静载反力装置主要是借鉴伞状地锚反力装置的连接方式,将锚桩的抗拔力作为反力来为试桩提供压力。在实际试桩工程中应用该装置,将会大大节省工期并降低施工成本,证明该装置具有广阔的应用前景。The conventional vertical compressive plate loading test is time-consuming and laborious,and there are hidden dangers in the test,so it need to be improved immediately.The new pipe pile plate loading opposite force device draw lessons from umbrella reaction device connection,the anti-pull force of the anchor pile is used as the reaction force to provide pressure for the test pile.The application of the device in a test bench of a substation greatly saves the construction period and reduces the construction cost,which proves that the device has wide application prospect.
