一、前言在进行填土的三轴试验时,通常是在试验室用扰动土制备成试样,试样制备的好坏直接影响三轴试验成果,因此,把好这头一关是十分重要的。本文介绍水科院用静压法制备粘性土或无凝聚性土试样时所使用的改进工具及操作方法,并介绍了含有少量细粒土的无凝聚性土试样的制备方法。 I. INTRODUCTION In the triaxial test of earth filling, samples are usually prepared in the laboratory using disturbed soil. The quality of the sample preparation directly affects the results of the triaxial test. Therefore, it is very important to take this first step. of. This article describes the improved tools and methods used in the preparation of cohesive soils or non-agglomerating soil samples by the Hydrostatic Institute, and also describes the preparation methods for non-agglomerated soil samples containing a small amount of fine-grained soil.
