摘要
针对嵌入式筒型结构在淤泥质海床上的工作机理,建立其在软土地基上的理论计算模型,提出适用于该模型的土压力、摩阻力、地基反力的计算方法,由静力平衡方程,求解得到维持结构稳定的水平极限荷载。通过ANSYS数值模拟软件进行分析,并通过荷载位移曲线找到结构发生倾覆破坏时的极限荷载,对理论计算进行验证。
A theoretical calculation model is established for the structure built on the soft-soil foundation according to the working mechanism of embedded cylindrical structure on the muddy seabed,and methods for calculating the soil pressure,friction resistance and subgrade reaction suitable for the model are proposed.The horizontal ultimate load to sustain the stability of the structure is obtained by solving with the equation of static equilibrium.Through the analysis by using ANSYS numerical simulation software and the load-displacement curve,the ultimate load that makes the structure overturn and destroy can be found out and the theoretical calculation model is verified.
