Test method applied to jet flow scouring of hard clay

A test method applied to hard clay jet flow scouring mainly comprises the following steps that clay slurry is loaded into a clay consolidation assembly, and the clay consolidation assembly is sealed; the negative pressure drainage assembly is started to dehydrate and consolidate clay slurry in the clay consolidation assembly; the dewatered and solidified clay is subjected to jet washing through a movable jet washing assembly; all the assemblies are disassembled, and the jet flow scouring test under one set of working conditions is completed. The method can greatly shorten the long-time consolidation drainage process of silt, carries out submerged jet flow on the remolded hard clay, can be used for researching the underwater scouring characteristics and the starting and diffusion rules of the hard clay, reveals the jet flow scouring mechanism of the hard clay, provides an evaluation method for the scouring capacity and the scouring efficiency, and has a good application prospect.
