摘要
针对目前带桩靴的自升式桩基平台插桩深度计算中存在的问题,通过考虑插桩过程中桩靴对地层物理力学性质的影响,运用最小二乘法求得桩靴对地层承载力的影响系数,从而对Terzaghi和Peck公式进行修正,提高插桩深度预测的准确性。
To discuss problems coming out in the calculation of footing tip penetration depth of the jack-up drilling platform, the influence effected to the physical and mechan ical characteristics in the soil stratum, into which the footing tips are penetrated, are considered. Then the influence coefficient of the footing tip effecting on the bearing ca- pacity in the soil stratum are estimated by means of the least square method in order to revise Terzaghi and Peck formulum. Therefore the footing tip penetration depth can be more accurately estimated.
