Abstract

The invention discloses a geotechnical centrifuge rainfall device, which comprises a model box at the bottom, a rain plate is installed on the top of the model box, the bottom of the rain plate is a porous plate, and a lattice structure; the rain plate is buckled with a cover plate, and the cover plate is sealed on the lattice structure; the rain plate and the cover plate are connected to the model box by bolts; A plurality of rain chambers are formed between the plate and the cover plate, and a plurality of atomization nozzles are installed on the cover plate, each of the rain chambers corresponds to one atomization nozzle, and the atomization nozzles are arranged on Corresponding to the center of the top of the rain chamber, each of the atomizing nozzles is connected to a water source. The present invention atomizes the water through the atomizing nozzle and evenly sprays it in the rainfall chamber, which can overcome the problem of uneven distribution of water in the high centrifugal field; Uniform rainfall was achieved in the inner test area.

Description

technical field [0001] The invention relates to a rainfall device, in particular to a geotechnical centrifuge rainfall device. Background technique [0002] Geotechnical centrifuge is a kind of test equipment used for physical simulation test of geotechnical engineering. The basic principle is to generate centrifugal acceleration through the rotation of the centrifuge arm, provide an artificial high gravity field, establish a model of a certain scale for the subject of research, and increase the self-weight stress of the soil through centrifugal acceleration to make the prototype and the model reach equal stress and strain. The deformation is similar to carry out simulation tests on the prototype. Landslides and collapses of various types and scales often occur on soil slopes under the action of strong rainfall or continuous rain. The stability of the slope is closely related to the rainfall. To study the working behavior of the slope under the rainfall condition in the ge...
