Abstract

Due to the anisotropy of sand, the sand will inevitably lead to different patterns of failure under principal stress axes rotation condition. It is necessary to research sand with different deposition angles. However, the existing sand sample preparation device of true triaxial apparatus only can prepare the specimen with 90 degree of deposition angle, which cannot meet the need for the true triaxial test to research the sand anisotropy. In this paper, I summarized the development of true triaxial sand sample preparation device, considering the limitations of previous designs, and introducing a novel visual specimen preparation device for true triaxial tests that can make the different deposition angles of layered sand. This visual specimen preparation device consists of three parts, a transparent bucket, a small funnel and a base with adjustable angle, which can prepare the sand sample with 15 degree, 30 degree, 45 degree, 60 degree, 75 degree and 90 degree.
