Horizontal permeameter suitable for soil horizontal contact surface shearing deformation

Abstract

The invention discloses a horizontal permeameter suitable for soil horizontal contact surface shearing deformation. The horizontal permeameter comprises a support, a test box arranged on the support, a sample chamber positioned in the test box, a vertical compression oil cylinder arranged on the top board of the test box, a transverse compression oil cylinder arranged on an outer side board of the test box, and an inlet water chamber and an outlet water chamber which are arranged at the two outer ends of the sample chamber along the piston action direction of the vertical compression oil cylinder, the inner side board at a water inlet end is formed by an upper transversely movable part and a lower fixed part, and a transverse compression oil cylinder piston acts on the transversely movable part. The horizontal permeameter can be used for researching the horizontal seepage characteristic and the horizontal contact surface wash destroy of a soil horizontal contact surface or a soil and structure horizontal contact surface under shearing deformation conditions.

Description

Technical field [0001] The invention relates to a penetration instrument for studying the seepage characteristics and erosion damage of the contact surface under the condition of shear deformation of the soil body or the contact surface of the soil body and a structure, and belongs to the field of geotechnical engineering test research. Background technique [0002] In geotechnical engineering, soil is the constituent material of a structure or the foundation of a structure. The soil is permeable, and various types of permeation damage may occur when it encounters water. The contact surface between different soil layers or between soil and structure is the most prone to seepage failure. The permeability and seepage failure of a single layer of soil can be measured by a conventional permeameter commonly used, but the seepage characteristics of the contact surface must be measured by a special permeameter. In particular, when the soil is subjected to shear stress and shear deform...
