摘要 本研究基于比奥理论，涉及有限厚度粘土层的二维和三维（多维）固结。作为分析结果，提出了沉降程度，并预测了沉降比太沙吉理论更迟缓的特殊现象。由于这似乎与曼德尔-克莱尔效应有关，因此对其物理原因进行了检查。通过考虑粘土的剪胀特性，定量讨论了超孔隙水压力及其时间历史。实验结果表明，如果考虑剪胀性，孔隙水压力的行为可以用Biot理论很好地解释。
ABSTRACT The present study is concerned with the two- and three-dimensional (multi-dimensional) «consolidation of a clay layer with finite thickness, on the basis of Biot’s theory. As the results of analysis, the degree of settlement is presented, and a peculiar phenomenon that the settlement is more retarded than that of Terzaghi’s theory is predicted. Since it seems the matter relevant to the Mandel-Cryer effect, its physical cause is examined. The excess pore-water pressure and its time history are discussed quantitatively, by taking account of the dilatancy characteristics of a clay. It is revealed from experimental results that the behavior of the pore-water pressure can be satisfactorily explained by Biot’s theory, if the dilatancy is taken into account.
