By a News Reporter-Staff News Editor at Health & Medicine Week -- Fresh data on Digital Imaging are presented in a new report. According to news originating from Zhejiang, People’s Republic of China, by NewsRx correspondents, research stated, “By means of the technology of particle image velocimetry (PIV), the physical modelings, using transparent sand and natural sand, were set up to simulate the shallow foundation, respectively. The transparent soil is composed of fused quartz and correspondingly refractive index-matched flammable liquid.”
Financial supporters for this research include Zhejiang Provincial Natural Science Foundation of China, Natural Science Foundation of Ningbo, National Natural Science Foundation of China, K.C. Wong Magna Fund in Ningbo University.
Our news journalists obtained a quote from the research from Ningbo University, “The flammable liquid is blended by two white mineral oils, Krystol40 and Puretol7. Transparent sand model was projected by a laser light sheet; meanwhile, the digital images of soil deformations caused by shallow foundation were captured. The PIV was employed to obtain the generated displacement fields from the digital images. The experimental results indicate that the deformation trends in transparent sand model are consistent with that in natural Ottawa sand model; however, the influential region is expanded by about 1.5 times, and the zone and magnitude of down-drag subsidence are extremely enlarged in transparent soil model, compared with those in Ottawa sand model.”
According to the news editors, the research concluded: “The verification of test results shows that the shallow strain path method is not suitable for the small-scale transparent sand and natural sand models.”
