| 摘 要： | 对印尼苏拉马都跨海大桥9根超长钻孔灌注桩采用自平衡法进行了静载荷试验.测试得到了桩端压浆前后的桩基承载力、桩端阻力及桩侧摩阻力.根据压浆前后的试验数据进行分析,压浆后桩极限承载力提高幅度为10.32%～170%,桩端阻力提高幅度为8.46%～207.6%,侧摩阻力提高幅度为8.32%～120%,整桩承载特性得到明显改善...

| Abstract: | Static load tests are carried out with Osterberg method on nine super-long bored piles formed in Suramadu Bridge.Bearing capacity,base resistance and friction resistance are obtained before and after base grouting.Based on the test results,the ultimate bearing capacity of pile is increased for 10.32%~170%,that of pile base is increased for 8.46%~207.6%,and the frictional resistance is increased for 8.32%~120%,therefore pile bearing behavior is improved.Not only base resistances are improved after grouting,b... |
