摘　　要：结合厦门环岛路木栈道桥墩加固工程,文章介绍了在分布较厚的砂层及中粗砂层、上空受限的狭小场地、坡度较大的潮汐地段等特殊工况下,采用高频液压振动锤进行的PHC管桩施工,详细描述了其施工工艺流程、高频振动锤施工频率选择,并通过桩基检测论证了方案的可行性。工程实践证明,该施工技术经济、简便、环保。Combined with Xiamen＇s Huandao Road bridge pier reinforcement engineering wood stack,the paper introduced the PHC pile construction by using the high frequency hydraulic vibrating hammer under the special working condition of thick sand layer and over constrained,narrow site slope of the tidal area. The construction process,frequency selection of high frequency vibrating hammer were described in detail,and the feasibility of the scheme was proved through pile testing. The engineering practice proves that the construction is economical,simple and environmental friendly.
