| 摘 要： | 根据野外现场调查和室内的实验资料,对红粘土的超固结性及低密实度和变形特征进行讨论,指出红粘土是超固结土,但同时密实度很低。超固结及低密实度的特征对土的变形性能也有显著的影响。还研究了红粘土超固结性和密实度及变形随土的埋深反常规变化的规律,并对红粘土的前期固结压力提出新的认识。

| Abstract: | Overconsolidation properties,low degree of density,and characteristics of deformation of red clay are discussed herein based on the data of field investigations and indoor test.It is stated that red clay is overconsolidation soil but its degree of density is low.Characteristics of deformation of red clay are influenced by overconsolidation properties and low degree of density.The abnormal rule of overconsolidation properties,low degree of density,and characteristics of deformation of red clay with soil depth of burial is studied.A new understanding of previous consolidation pressure of red clay is proposed. |

| Keywords: | red clay overconsolidation degree of density deformation previous consolidation pressure |
