| 摘 要： | 在侧限条件下,对物理性质相同的土分别采用静力和冲击作用产生相同的预压密,对预压密后的土样进行高压固结试验,对比研究压密程度相同但成因不同的预压密后土的压缩曲线、前期固结压力和压缩指数。结果表明,相同预压密的土,压缩后土的压缩指数相近,与预压密的成因无关。而压缩曲线和前期固结压力则因土类而异,经历相同预压密后,不饱和粉质...

| Abstract: | High-pressure oedometer tests were conducted on soils pre-densified with the same amount of vertical deformation formed by static load and impact load under confined compression conditions.Compaction curves,preconsolidation pressures and compression indexes of same pre-densification deformation soil formed in different way were comparatively investigated.The results showed that compression indexes of same pre-densification soil were close and irrelevant to the cause of pre-densification;compression curves a... |
