摘要
自升式平台应用日益广泛,如何预估地基土的承载力以使平台安全作业,是需要解决的关键问题。研究了ABAQUS中土的弹塑性模型及进行数值模拟的条件等内容,应用土力学理论和有限元数值模拟两种方法,对自升式平台桩靴所受的垂向作用力进行对比分析。采用ABAQUS软件研究桩靴入泥深度和贯入阻力之间的变化规律,讨论了土体参数对桩靴贯入阻力的影响规律,得出具有一定意义的结论。
Jack-up platform,in the recent decades,has got widely used.How to forecast the bearing capacity of soil to make it work safely is a critical issue.The elasticity-plasticity model of soil in ABAQUS and conditions of numerical simulation are researched,two methods,formulas of soil mechanics and finite element numerical simulation are adopted in this research.The vertical bearing capacity of the spud foundations is compared and researched.And by the ABAQUS,the vertical resistance-penetration responses on the penetration resistance are studied and different influencing factors on the penetration resistance are discussed,valuable conclusions are got.
