简要地报道对不含水土层分层排列、饱水土层分层排列、不含水土层与饱水土层分层交错排列情况下对波传播和地面运动影响的研究结果．考虑到土场的剪胀性、线性和非线性本构关系、刚度退化等因素，编制了可适用上述各种情况和任意多土层（包括含水或不含水、力学性质不同、厚度不同、边界连续条件不同等），在不同基底输入或上边界输入作用下的通用分析程序．通过对相当数量的典型情况进行的分析计算，得到了一些趋势性的认识，特别是对饱水与不含水土层分层交错情况，取得了一些认识．

EFFECT OF ALTERNATE DRY AND SATURATED SOIL LAYERS ON GROUND MOTION AND WAVE PROPAGATION

A brief introduction is made of the results obtained by the authors for the subject of various effects on wave propagation and ground motion of muhlti-dry,muhlisaturated,and alternate dry and saturated soil layers.A comprehinsive computerprogram is compiled,accouonting for soil dilatancy,linear and no-linear constituti ve relation,rigidity degradation and suiting to any combinations of soil layers, dry and/or saturated with different thicknesses,properties,continuity conditions at inte rfaces,and inputs at base and top boundaries.From the numerical results obtained for a quite large number of typical typical cases,some knowledge of general trends of response for, especially,the cases of alternate dry and saturated soil layers are gained both quantitatively and qualitatively.Therefrom,some conclusions and suggestions are presented.
