施工技术 2013年7月上 24 CONSTRUCTION TECHNOLOGY 第42卷第13期 D0I:10.7672/sgjs2013130024 无锚杆静压桩在某地基加固中的应用 郑育新 (四川建筑职业技术学院土木工程系，四川德阳618000) [摘要]无锚杆静压桩即压桩架下无需植错杆，而是将压桩架用穿墙螺栓紧固于墙体上，施工方便快捷，因不需要 植锚杆而工程成本相对较低，工期更短.该技术特别适用于多层砖混结构建筑中的砖砌大放脚基础，因砖砌大放 脚基础往往不具备埋设错杆和安装锚杆静压桩压桩架的条件.由于本技术压桩架紧固于墙体上，稳固性强，利用 卡在压桩架上的滑动桩帽与基础垫层中的压桩孔，易于控制桩的垂直度，使静压桩在含卵石的土层中也易于压桩 加固施工.
