| 内容記述 | This paper presents numerical examples demonstrate a capability of method of estimating the elastic properties of the soils and their variation with depth using the characteristics of P-SV wave fields caused in the surface of an elastic multi-layered half space by the vertical harmonic point load applied also on the soil surface. In this numerical examples, the three cases of ground model are used the models of typical shallow surface ground: case 1 is a nomal soil deposit where soil properties increase with their depth from the ground surface while case 2 and 3 are the irregular soil deposits. In case2, the second layer is a low velocity layer and in case3 it is a high velocity layer. In this paper, the unknown parameters that estimate by the proposed method are the thicknesses of the soil layers and their S and P wave velocities. In the numerical examples, the stiffness matrix method is used for an accurate simulation of all P-SV wave fields. | |||||
