主 题:Soil-structure interaction Time domain Wave propagation Wavelength Infinite domain Perfectly matched discrete layer(PMDL)
摘 要:Analysis of soil-structure interaction is commonly conducted by dividing the infinite domain of the soil into two domains:interior and exterior *** interior domain is bounded in a small region,while the exterior domain is replaced by artificial boundary *** choice of artificial boundary conditions is a critical issue in the analysis of soil-structure interaction *** matched discrete layer(PMDL)has been proved as a good approach for modeling the exterior *** this study,a modified version of the PMDLs,*** with analytical wavelengths(AW-PMDLs),is used in the soil-structure interaction analysis in time domain,which essentially can be regarded as an extension of the analysis in frequency domain,being previously proven to be *** verifications are *** results demonstrate that the proposed method performs well in the analysis of soilstructure interaction problems in time domain.
