南海海域深水导管架平台桩土力学分析

Pile-soil Mechanical Analysis of Deep-sea Jacket Platform in South China Sea

以番禺30-1号导管架平台为原始模型,针对南海北部水文,以及南海北部陆架区海底土性质,采用设计波法设计海洋环境载荷,进行导管架平台群桩桩土力学分析。对比分析竖直桩和10°倾斜桩的轴力、横向位移、应力以及截面剪力力学性能,发现斜桩的力学性能优于竖直桩。

Taking PanYu 30-1 jacket platform as the original model, according to the hydrology and the seabed soil properties of continental shelf in northern South China Sea, the marine environ- mental loads with the design wave method was designed and pile-soil mechanical analysis of jacket platform group piles was conducted. A comparison of mechanical properties was also made including axial force,displacement,stress and shear between the vertical group piles and the 10° inclined group piles,and it was found that mechanical properties of inclined group piles are superior to those of vertical group piles.
