摘　　要：上海暗绿色粉质粘土是上海桩基础的持力层。对这层土土样的局部化变形和剪切带形成规律的试验研究将有助于它的基本性状的深入。本文介绍改装的平面应变仪 ,并通过对该层粘土在固结不排水平面应变压缩试验结果的分析研究 。The dark green silty clay in Shanghai is a bearing stratum for pile foundation. Tests and researches on the local deformation of this stratum and on law of formation of shear zone will conduce to further study of its basic behaviours. A plane strain apparatus which has been modified is introduced herein. Through analyzes on the results of consolidated undrained plane strain compression of the said stratum laws of formation of shear zone is proposed quantitatively.
