| 摘 要： | 由于福州市龙泉大厦(新都会花园广场)地基覆盖层厚、岩土种类多、下伏基岩火成岩(花岗岩、花岗斑岩)风化岩面起伏大，其基础型式设计为钻孔灌注桩(嵌岩桩)，针对复杂地层中超深钻孔桩(设计平均桩长大于50m)施工的技术难点及采用的技术措施进行了系统的总结，为今后类似项目的施工提供了成功的范例。 |
| 关 键 词： | 灌注桩 超深 复杂地层 施工技术 |

| Abstract: | Because of foundation of Longquan Building, Fuzhou has thick overburden layer, wide variety of rock and soil, undulated weathering face of underlying igneous rocks (granite, granite porphyry), its basic designed pattern is borehole filling pile (cast-in-place pile). Aimed at technical nodi in super-deep borehole pile (designed average pile length more than 50m) technical measures carried out systematic summary, provided successful showpieces for similar project henceforth. |
| Keywords: | filling pile super-deep complicated strata engineering technique |
