Abstract

The invention discloses a simulation test device and method for a loose media underwater hardening law. A sample fixture adopts semi-annular metal pieces, and densely arranged pinholes are formed in the semi-annular metal pieces. The assembled sample fixture is fixedly arranged on a base. A bottom cover is arranged on the end surface where the base makes contact with the sample fixture. A top fastener is arranged on the top of the sample fixture, and a top cover is arranged on the end surface where the top fastener makes contact with the sample fixture. The base, the sample fixture and the topfastener are detachably and fixedly connected by a locking device. A plurality of the sample fixtures are integrally placed inside a closed container, and a closed container top cover is arranged onthe top of the closed container by fixing bolts. An air inlet pipe, an air exhaust pipe and a pressure gauge communicate with the closed container top cover. The simulation test device and method areused for simulating and studying the change of the occurrence state of solid phase sources and the change of the mechanical and physical properties of the solid phase sources with the passage of timeand under environment action under the coexistence of solid phase sources and liquid phase sources.

Description

technical field [0001] The invention relates to a simulation test device and method for the underwater compaction law of loose bodies, belonging to the technical field of hydropower test equipment, and can be applied to research on the influence of silting objects on the operation of hydraulic structures in hydropower projects and the operation of hydropower equipment near water. Background technique [0002] As for the compaction test of soil or soil rock, at this stage, more studies are carried out on the mechanical test of the source of compaction and the research on anti-compaction and cracking of compaction, and less about the compaction process and Regular research results. [0003] The more common research results at this stage are the rock degradation simulation test devices, such as the indoor rock mechanics test under the action of water-rock to study the coexistence of rock and water, different water pressure environments or the degradation effect of rock under th...
