摘　　要：根据粘性土室内侧限压缩试验曲线,理论上推导出地基土在实际受荷压力段的压缩模量当量值,并考虑原土结构性和有效应力损失等因素对该值进一步修正,得到可塑～坚硬状粘性土压缩模量比较合理的数值。According to the consolidation curve of the cohesive soil, the theoretic value of the constrained modulus of the subsoil within the soil pressure realistic range is deduced, and the reasonable value of constrained modulus of cohesive soil ranging from plastic to hard is derived with the further consideration of several modification factors including the structure of the natural soil and the loss of the effective stress.
