Prestressed high-strength concrete (PHC) pipe pile hammering method construction initial parameter adjusting method
According to the PHC tubular pile hammering method construction initial parameter adjusting method, single pile hammering energy with the single pile vertical bearing capacity characteristic value being 1.05-1.20 times of the designed bearing capacity characteristic value serves as lower limit hammering energy and upper limit hammering energy analysis statistical data of hammering method piling; and the total hammering energy and the single-pile average hammering energy of the pile foundation in the upper limit interval and the lower limit interval are calculated, so that it is guaranteed that the bearing capacity of the pile foundation meets the design requirement, the bearing capacity redundancy of the pile foundation is limited, and the situation that the integrity of a pile body is damaged due to the fact that the hammering energy of the PHC pipe pile is too large is prevented.
PHC管桩锤击法施工初参数调整方法，以单桩竖向承载力特征值为1.05‑1.20倍设计承载力特征值的单桩锤击能，作为锤击法打桩的下限锤击击能和上限锤击能分析统计数据；计算上下限区间内桩基的总锤击能和单桩平均锤击能，从而保障了桩基承载力满足设计要求，并限制了桩基承载力冗余度，防止PHC管桩因锤击能过大而破坏桩身完整性。
