ABSTRACT: This paper presents recent advances in physical simulation in earthquake
geotechnical engineering at Tsinghua University, including three new developed testing
apparatuses and their specifications.
DEVELOPMENT OF A HYDRAULIC SHAKING TABLE ON A CENTRIFUGE
The m effective radius single-platform centrifuge at Tsinghua University was built
in 1993 (Pu, et al. 1994). The centrifuge (Figure 1) has a capacity of 50 g-tonne and can carry
a payload of up to 200 kg at 250 g. The swing-up platform has an envelope of 70 × 60 × 70
cm. The research areas of centrifugal modeling at Tsinghua University include: (1)
development of new instrumentation; (2) stability analysis of embankment and slopes; (3)
foundation engineering; (4) tunneling; (5) cold region engineering; (6) geoenvironmental
engineering; and (7) earthquake geotechnical engineering.
