| Abstract: | 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. |
