| 摘 要： | 近年来,在对国内广泛分布的老粘性土、红土等土体的研究过程中发现,这些土均为＂超固结土＂,其先期固结压力（Ｐｃ）值不仅与土的受荷历史有关,而且还与土的物质组成和结构特征有着十分密切的关系。研究结果表明,影响Ｐｃ值大小的因素很复杂,红土和下蜀土中对Ｐｃ值大小起决定作用的为游离氧化物的胶结连结,而黄土状土中土自重压力则为主导因素。可见土的先期固结压力并非唯一由上覆荷载所致。

| Abstract: | The paleo-clay and red soils belong to "overconsolidated soil",the preconsolidation pressure is not only related to history of load but also related to compsition and structure of soils. There are many factors that inflence Pc value,and Pc value of Xiashu soil and red soils affects cement of free oxides,Pc value of loessial soil affects overburden pressure,so many factors affect preconsolidation pressure of soils,load is only one reason. |
