摘要面波谱分析是一种简单而有效的方法，可用于确定现场土的剪切波速及其随深度的变化。该方法的非破坏性特征，以及通过让重物从一定高度落下而产生长波长的可能性，使其成为一种非常合适的技术来获得剪切波速度剖面，而不需要钻孔。在本文中，举例说明了该方法如何在西班牙用于确定压实的填料和垃圾填埋场的变形能力，评估冲积沉积物的液化潜力，描述地基和堆石坝的地质力学行为，确定岩石隧道衬砌后蚀变带的范围，并判断某些地层的改善程度治疗。
Abstract Spectral analysis of surface waves is a simple and efficient method of determining the shear-wave velocity of soils in situ and their variation with depth. The non-destructive character of the method, together with the possibility of generating long wavelengths by letting a weight drop from a certain height, makes it a very suitable technique to obtain shear wave velocity profiles without requiring the drilling of boreholes. In this paper, examples are given of how the method has been used in Spain to identify the deformability of compacted embankments and waste landfills, to assess the liquefaction potential of alluvial sediments, to characterize the geomechanical behavior of foundations and rock-fill dams, to determine the extent of the alteration zone behind the lining of a tunnel excavated in rock and to judge the degree of improvement achieved in some ground treatments.
