Abstract

The influence of local geotechnical site conditions on the soil profile amplification is analysed in this paper by assuming that the incoming seismic waves consist of inclined P-SV waves. The inhomogeneous soil profile is idealized as a multi-layered saturated poroviscoelastic medium and characterized by the Biot’s theory with a shear modulus varying continuously in depth according to the Wichtmann’s model. The results are presented in terms of horizontal and vertical soil profile amplification with linear and nonlinear soil behaviour, for different values of incidence angle, pore-water saturation, porosity, permeability, coefficient of uniformity, and non-cohesive fines content.
土性质对饱和非均匀孔粘弹性土剖面放大的影响
本文在假定入射地震波为倾斜P-SV波的情况下,分析了当地岩土场地条件对土体剖面放大的影响。将非均质土剖面理想化为多层饱和多孔粘弹性介质,其剪切模量根据Wichtmann模型随深度连续变化,符合Biot理论。在不同入射角、孔水饱和度、孔隙度、渗透率、均匀系数和非粘性细粒含量的情况下,以线性和非线性土体特性的水平和垂直剖面放大结果为例进行了分析。
