摘要
对上海两层主要粘性土层的原状土样在研制的平面应变仪上进行固结不排水平面应变压缩试验 ,量测土样的局部变形 ,研究局部化应变的发展规律 ,为研究土体剪切带的形成提供有益的试验资料。
With new developed plane strain apparatus, a series of consolidated undrained plane strain compression tests were carried out on undisturbed clay samples of two main clayey layers. The local deformation of samples was measured and the regularity of localized strain evolution was studied. The study supplied useful information for the research of shear band formation in soil mass.
