Problems solved by technology

Because it only simulates the influence of the single factor of water level change, but ignores the influence of complex working conditions caused by multiple factors in the real environment, the experimental results cannot correctly reflect the actual engineering problems.

Abstract

The invention relates to a geotechnical centrifugal field rainfall and water level change working condition simulation device and method. The device comprises a model box driven by a centrifugal machine to rotate, wherein a model is arranged in the model box; a water storage box is arranged at the upper part of the model box; a water conveying pipe is arranged between the water storage box and themodel box; water in the water storage box is conveyed into the model box by the water conveying pipe so as to control the water level in the model box to ascend; an atomization spray head is arrangedabove the model; the atomization spray head simulates the rainfall process, and the water in the water storage box is sprayed onto the model; a water collecting box is arranged under the model box; the model box discharges water in the box into the water collecting box through a water discharging opening. The complicated work conditions such as water level rise, water level rise caused by rainfall can be simulated; the experiment data accuracy is improved; through the arrangement of the atomization spray head, the uniform covering of the model rainfall region is realized; the slope surface destroy caused by flushing due to too great raindrop is prevented.

Description

technical field [0001] The invention relates to the technical field of geotechnical centrifugal model equipment, in particular to a device and method for simulating rainfall and water level changes in a geotechnical centrifugal field. Background technique [0002] The load and stress of the geotechnical structure are mainly produced by the weight of the structural medium itself, and at the same time dominate the deformation and failure of the geotechnical structure, which is a remarkable feature of geotechnical engineering. People often reveal and analyze the nature and mechanism of phenomena through field tests and indoor small-scale physical model tests to verify theories and solve practical engineering problems. Geotechnical centrifuge is a kind of test equipment used for physical simulation test of geotechnical engineering. Its basic principle is to generate centrifugal acceleration through the rotation of the centrifuge arm, provide an artificial high gravity field, and...
