摘　　要：福建属于沿海吹填砂造陆码头地区,文章通过对该地区某工地旋挖成孔灌注桩基础3根未注浆桩和3根后注浆桩的单桩竖向抗压静载试验研究,得到了大吨位静载试验中未注浆桩和后注浆桩的荷载-沉降关系、桩身压缩占桩顶沉降的百分比,并基此探讨了后注浆技术、桩身压缩对桩基承载力及沉降的影响。At one construction site of sand reclamation wharf area of Fujian province, vertical compressive static load tests on three bored piles without post - grouted and three bored piles with post - grouted were conducted. Based on the Large - tonnage static load tests of six bored piles, the load - settlement responses and compression of the pile shaft of six piles were analyzed. Furthermore, the effect of post - grouting technology and compression of the pile shaft on bearing capacity of pile were discussed.

关 键 词：灌注桩 静载试验 后注浆技术 承载力 沉降
