Research on Effect of Spudcan Penetration and Extraction of Jack-up Drilling Platform on Deformation and Spudcan Bearing Capacity of Adjacent Platform
The spudcan penetration and extraction process of jack-up drilling platform disturbs the surrounding soil,which adversely affects the bearing performance of the spudcan foundations of the adjacent platform.Based on the elastic theory,the unloading degree and influence range of the soil around the spudcan footprint are solved.Combined with the model test,the soil strength attenuation law under different L/D conditions from the penetration and extraction position is revealed.The spducan penetration and extraction process of the jack-up drilling platform is analyzed by the CEL and the quasi-static calculation method.The influence law of spducan penetration and extraction on the surrounding soil stress,the deformation and the spudcan bearing capacity of the adjacent platform is revealed.
