Abstract

Unprecedented opportunities and challenges have been confronted in geotechnical engineering practices in the context of all infrastructure in large-scale and high-speed construction of infrastructures in China. Large test equiments represented by geotechnical centrifuge has been developed rapidly, providing important tools for theoretical researches and practical problem-solving. To promote the standardization of centrifuge modeling techniques and its application in the practice, at the same time, to expand influence of centrifuge modeling techniques in the engineering, the parallel tests on geotechnical centrifuge modeling are carried out in China, including the preparation of sand stratum model, bearing capacity of pile foundation as well as slope stability. The relevant experimental results among 8 institutions, for preparation of samples with sand pourer are introduced. Fujian standard sand is chosen as the experimental material, the type of sand rainner outlet, includes cylindrical mesh type and linear duckbill type, and the shakeout device is prepared by each participant institution. Based on the
- model test,
- sand pourer,
- standard sand,
- relative density
