Abstract
An embeddable seepage module capable of being embedded into an interface ring shear apparatus is disclosed, wherein: the seepage module includes an annular cylinder, a seepage pressure regulation system, a top plate and a bottom plate; the interface ring shear apparatus includes an upper shear box and a lower shear box; the annular cylinder, the top plate, the bottom plate, the upper shear box and the lower shear box form an internal pressure cavity and an external pressure cavity; the internal pressure cavity is able to realize the precise double control of the soil seepage pressure and water flow through the seepage pressure regulation system; the external pressure cavity is able to collect fine soil particles under pressure seepage. In the case of soil seepage-shear coupling, the seepage module is assembled firstly for seepage, and after completing the seepage, the external pressure cavity is removed for ring shear tests.
