000010671 520__ $$2eng$$aBased on the damping solvent extraction method (DSEM), a new sub-regional explicit-implicit reciprocal solution method with integral strategy of mixed time step-size in time domain is proposed in this paper, to cope with the numerical analysis of dynamic soil-structure interaction. In the approach, an implicit integral arithmetic with big time step is applied in the computation of structure region, as explicit integral solution with small time step is used in the soil region. This method is convenient to combine the numerical advantages of big calculated time steps in implicit integration and wide applicability of explicit numerical integration. Furthermore, according to the similarity in the numerical expression between dynamic differential equations for structure and fluid mechanics, the above proposed solution methods on DSEM is extended to cope with the dynamic dam-reservoir interaction, in which the hydro dynamic pressure of unbounded water can be presented by explicit boundary interaction forces. Finally, some practical examples are presented to demonstrate that the evaluation efficiency can be efficiently improved in the condition of satisfying good engineering accuracy.
