I990 years Auersch, Sehmid The role of shear walls, and put forward a simple formula. 1992 Wang and Schmid The results showed that: the two-dimensional, three-dimensional results obtained with different models, features are very different, with two-dimensional soil model can not simulate three-dimensional problem of wave propagation; consider the interaction of increased displacement, basic form is an important factor, basis have a greater surface displacement,<a href="http://www.edhardymexicos.com" target="_blank" class="postlink">Ed Hardy mexico</a>, which produce a smaller amplitude buried foundation. 1992,<a href="http://www.mulberrytaskeroutlet.com" target="_blank" class="postlink">mulberry tasker</a>, Wang no loss of accuracy, the discrete free surface of soil foundation for the embedded base of the vibration characteristics than the surface to be significantly affected. On the frequency domain method for solving coupled pile soil interaction problem, Zhang, Lu and other have done some research, can be found in References. Time domain method: Manolis, Beskos, Sparakos in the early eighties boundary element method, soil, static structure, has done a lot of dynamic interaction problems,<a href="http://www.toryburchukshoes.com" target="_blank" class="postlink">Tory Burch UK</a>, then the boundary element, finite element coupling has to do time-domain law some work and Beskos 1985 Karabalts time domain method to do a three-dimensional flexible foundation and soil interaction analysis. 1986 Sparakos and Beskos Estorff in the time domain method in recent years has done more work. 1989 Estorff and Kausel 1992 Estorff. . Coupling method for evaluating the effectiveness of write articles, and gives examples of representative numerical calculations. Estorff proposed to use only part of the boundary element time step of the process, and with the sub-structure method were compared; shows the accuracy of time-domain coupling method presented in different forms such as linear per unit, the second element, and other kinds of discrete Methods for the parameters, and when asked on the computing time step, calculation results are compared, the results that the coupling method and the time-domain boundary element method results are almost the same. Using linear or quadratic boundary element coupling does not affect the results, in order to reduce the amount of the boundary element of the unknown can be a rough boundary element mesh,<a href="http://www.abercrombiemilanohollister.com" target="_blank" class="postlink">abercrombie outlet</a>, the same good results can be obtained. The results also show that the coupling method for the boundary element method to save more when asked. Estorff also proposed interaction effects of neighboring systems,<a href="http://www.oakleyoculoss.com" target="_blank" class="postlink">Oakley juliet</a>, the two structural systems are given in the horizontal and vertical dynamic case, the distance between two adjacent structure, the impact of research in this area mentioned above are interactions issues important topics.
