为了不使基桩在地震作用下由于节点的薄弱而提前失去承载能力，结合室内拟静力试验，对不同节点加强方式的管桩承台节点模型进行了水平承载力试验研究。对比了在节点处设置加强环和将普通填芯换做劲性填芯的试件节点的抗弯能力、裂缝发展情况和破坏模式，并依据实测的破坏荷载得出了相当于普通填芯混凝土管桩的桩体嵌入承台的深度，分析比较了试验试件与等效试件的裂缝发展情况和破坏形式，为桩基抗震设计提供参考和帮助。

In order to make sure the node of piles and cap provide enough carrying capacity during the earthquake, the nodes with different enhanced filled concrete pile under the quasi-static loading conditions are studied. The bending strengths, crack development and destructive mechanism of specimen nodes with setting ring at the node and replacing common core to stiff fill core are compared. The equivalent embedded depth of pile into the cap is calculated based on the experimental results of failure loadings. The experiment results can provide a reference to the seismic design of concrete pile node.
