Abstract

The invention relates to a centrifugal model test device and test method for simulating erosion of toes of a reinforced earth retaining wall. The test device comprises a model test box, The reinforcedsoil retaining wall model comprises foundation soil laid at the bottom of the model test box, a reinforced soil retaining wall arranged in the middle of the foundation soil, and filling soil which iscompacted and filled in a cavity defined by one side of the reinforced soil retaining wall and the side surface of the model test box. The reinforced soil retaining wall is composed of a horizontal base buried in foundation soil, wall surface modules laid on the horizontal base layer by layer and a plurality of layers of rib materials which are horizontally laid in filled soil from top to bottomand connected with the wall surface modules. The device comprises a sand suction mechanism and a high-speed camera. Compared with the prior art, the device has the advantages that the evolution of thestress characteristics of the reinforced earth retaining wall under the influence of water flow erosion and the deformation and damage process of the retaining wall can be studied more economically,conveniently, reliably and intelligently in a laboratory.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering tests, and relates to a centrifugal model test device and a test method for simulating the erosion of the toe of a reinforced earth retaining wall. Background technique [0002] In the 1960s, French engineer Henri Vidal proposed the concept of "reinforced soil", and the reinforced soil retaining wall came into being. Compared with the traditional gravity retaining wall, cantilever retaining wall and buttress retaining wall, the reinforced earth retaining wall has the advantages of low cost, simple construction, beautiful appearance, high stability and good seismic performance. It has developed rapidly and has been widely used in engineering construction in the fields of construction, transportation, water conservancy and land resources. Reinforced soil retaining wall is a good flexible structure, which has a certain degree of deformation resistance unde...
