| 摘 要： | 工程实践证明,软土地基超长桩在轴向荷载作用下的荷载传递机理与常规桩基有较大区别。通过深厚软土区超长桩静载试验和桩身轴力测试,依据载荷-沉降变形关系推导的超长桩合理桩长估算公式,利用静载试验Q-S曲线数据对超长桩合理桩长进行计算,为确定深厚软土地区合理桩长避免盲目增加桩长提供参考。

| Abstract: | Engineering practice has proved that the super-long pile with axial loads in soft soil area is quite
different from the conventional pile foundation in load transfer mechanism. Through static load and pile shaft force test of super-long pile in deep soft soil area, proper pile length estimation formula of super-long pile is deduced according the load-settlement deformation relationship. Using Q-S curve static load test data, the proper pile length of super-long pile is calculated. |

| Keywords: | deep soft soil area super-length pile proper pile length static load test Q-S curve |
