Firstly, the meaning of dynamic analysis on the steam turbine-generator set foundation is pointed out. Review and comment on the present research on dynamic analysis of domestic and international steam turbine-generator sets are presented Then a dynamic calculating model of the framed foundation of the steam turbine-generator set is set up based on finite element theory. Then dynamic analysis methods are put forward based on dynamics theory. The dynamic design of the foundation of the specific 12,000KW steam turbine-generator set is carried out.

The results of numerical analysis show that the elastic modular and the poisson ratio have no effect on two-dimensional bearing capacity, but can affect the ultimate bearing capacity of three-dimensional foundations and control the convergence and precision of finite element calculation; the earth pressure coefficient controls the geostatic stress of foundation, sequentially affects the ultimate bearing capacity of foundations and the convergence of numerical calculation. When calculating the ultimate bearing capacity of undrained saturated foundation, the complete formulation exists shear locking, and reduce formulation exists hourglassing, so the hybrid formulation is suitable to imitate the geomaterial. When the soil obeys nonrelevent flow rule, the yielding function is different from potential function, and the elastic-plastic matrix of soil is asymmetric, so the unsymmetry numerical solver and appropriate finite element mesh is required.

研究结果表明，土体弹性模量和泊松比对二维基础极限承载力没有影响，但是影响着三维矩形基础的极限承载力，控制着ABAQUS数值算法的计算精度与收敛速度；地基土压力系数控制着地基土体中的地应力平衡，从而影响着二维条形基础和三维矩形基础的极限承载力和地基破坏包络面；对于不排水饱和软黏土地基，常规的完全积分单元会造成剪力自锁现象，而减缩积分单元则存在过于柔化的现象，故采用杂交单元来模拟较合适；当土体服从非关联流动法则时，屈服函数与塑性势函数之间存在差异，从而导致土体弹塑性矩阵呈现非对称性，在有限元计算中必须采用非对称数值解法，并且合理地划分单元才能对极限承载力进行准确求解。

To control the base design of power machine using numeric,taking the blower as an example,the key problem affected by power machine load,base and subgrade-the off-center value between centroid of control load and poid of foundation subface was analyzed.The relationship of calculating maximum amplitude of machine foundation and permitting amplitude was discussed.
