摘　　要：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。Through the static load test of super-long piles and the axial force test in deep soft soil area, based on the estimation equation of reasonable long of super-long piles derived by load-settlement deformation relationship, the reasonable length of super-long piles is calculated by Q - S curve data of static load test, and it provides the references for determining the reasonable pile length and avoiding blindly increase the pile length in deep soft soil area.

关 键 词：深厚软土区 超长桩 合理桩长 静载试验 Q-S曲线
