前言目前,迫切需要有一个简化的方法来估计土坝和地基的地震枝定性。随着这种方法的发展,需要更多的实践中可迂到的各种土,在往复荷载下抵御变形或液化的室内试验资料。事实上,目前很多已发表的试验资料是研究有关松散的或中等密度的、级配不好的正常固结 Foreword At present, there is an urgent need for a simplified method to estimate the seismic branch characterization of earth dams and foundations. With the development of this method, more soils that can be picked up in practice are required to withstand the deformation or liquefaction of indoor test data under reciprocal load. In fact, many of the published experimental data are currently studying loose or medium density, poorly grading normal consolidation.
