Description
Technical field
The invention belongs to centrifuge technique fields, and in particular to a kind of high speed geotechnical centrifuge structure.
Background technique
From 1931 in the world First radius be 0.25m geotechnical centrifuge Columbia Univ USA be born with
Come, the development through many decades, the whole world is completed more than 200 platform of geotechnical centrifuge.By being produced using geotechnical centrifuge high speed rotation
Raw super gravity field can effectively solve the reduced scale problem of modelling of geotechnical model, using model true reappearance civil engineering
Prototype characteristic provides effective means to study practical civil engineering problem.
Currently, the maximum centrifuge of the capacity built up in the world is to be US Army work French Actidyn company nineteen ninety-five
Journey Shi Bingtuan water channel experiment station (WES) builds up 1144gt centrifuge, the centrifuge radius 7m, maximum centrifugal acceleration 350g.
The maximum geotechnical centrifuge of the capacity that the country is built up is that Chengdu science and engineering carried out by Chinese physical engineering research institute system engineering research is big
The 500gt geotechnical centrifuge developed is learned, maximum centrifugal acceleration is 250g.
With the development of science and technology, the mankind it is long to pollutant underground last migration, Hydrocarbon Formation Reservoirs, geological structure develop,
The significant problems such as new material high throughput preparation conduct a research, and urgent need capacity reaches 1500gt (to be indicated, wherein g adds for gravity with gt
Speed, t are mass unit: ton), centrifugal acceleration reach the high speed geotechnical centrifuge of 1500g.
Existing geotechnical centrifuge can carry out conventional centrifuge model test, and achieve preferable effect.But most because of it
Large capacity is limited, and the test model of carrying is smaller, meanwhile, maximum centrifugal acceleration is relatively low, also cannot be lesser test
Model provides biggish centrifugal field.It can be seen that existing geotechnical centrifuge does not have the weights such as geological changes, environmental contaminants migration
Big scientific research project carries out the ability of test simulation.
