摘要
针对三筒吸力式导管架基础在粉砂质土、淤泥质土中的承载特性进行一系列的数值研究。选取不同厚度的粉砂质土和淤泥质土组合,利用ABAQUS有限元软件对不同土质组合下基础单向的水平承载能力、破坏特性和吸力筒的临侧土压力进行分析。研究发现:三筒吸力式导管架基础在不同土质组合下的水平承载能力呈规律性的变化,且随粉砂质土厚度的增加而增大。结构承载力在吸力筒侧壁的粉砂质土厚度为3~6 m时表现出最大的增长能力,研究结果可为实际工程中三筒导管架基础设计提供建议和参考。
In this paper,a series of numerical studies on the bearing capacity of the tripod jacket foundation in sandy soil and silty clay are conducted.The combination of sandy soil and silty clay with different thicknesses is selected,and the general finite element program ABAQUS is used to analyze the bearing capacity of the foundation,the failure characteristics of the foundation and the soil pressure on the side of the cylinder under the horizontal load with different soil combinations.The calculation results show that with the thickness of the silty soil increasing,the horizontal bearing capacity of the tripod suction jacket foundation is regularly increased.The structural bearing capacity shows the greatest growth when the thickness of the attached silty soil is 3-6 m,which can provide suggestions and references for the site selection of the tripod jacket foundation in the actual project.
