摘要

摘要分析了饱和水砂土在瑞利面波传播引起的动荷载作用下的特性。饱和砂土基质在地面运动作用下的循环剪切作用导致了土体超孔隙压力的发展及其随后的液化。在饱和颗粒介质压实理论的框架下,研究了孔隙压力的产生和土壤液化现象。采用有限元方法进行的计算结果显示了土中孔隙压力的演变和液化区的发展,并显示了表面波参数随地基强度的逐渐退化而变化。

Rayleigh Waves Transformation in Liquefying Water-saturated Sands
Abstract The behaviour of a water-saturated sand deposit subjected to dynamic loads induced by the propagation of Rayleigh surface waves is analysed. Cyclic shearing of the saturated sand matrix due to ground motions results in the development of excess pore pressures in the soil and its subsequent liquefaction. The phenomena of pore pressure generation and soil liquefaction are investigated within the framework of a compaction theory for saturated granular media. The results of calculations, carried out by a finite-element method, illustrate the evolution of pore pressures and the development of liquefaction zones in the soil, and show the variation of surface wave parameters with the progressive degradation of the strength of the subsoil.
