Abstract
In this paper, an approximate solution which is taking the elfect of diffracted waves into account is presented for the surface ground motion Qf a dippingIlayer . 』 It iSi based on しhe ray theory . This method cosidered the wave component whlch propagated along the surface from the egde of a dipping Layer as diffracted waves . Comparison of results w .ith the boundary element method shows very good agreement at lower computational cost . Frequency responces and time domain results are presented for.diflerent property contrasts and inciClence angles . This method is suited to study for the surfac β response of analysis of dipping layer, due to its low cost and no upPer frequency limit . . ・ Kegwonts :ray thllory , diff 厂acted wave , amptitude discontinuity ,漉卿 η9 勿 σ 波線理論,回折波,変位の不連続量 ,傾斜層
