Abstract
The paper presents a shaking table test aiming to explore seismic response characteristics and earthquake damage mechanism of utility tunnel systems. The experiment was done on a 3 m × 3 m shaking-table, and three seismic acceleration records were selected as input motion. A utility tunnel model with the scale of 1:10 was built up based on statistics of the popular utility system in China, which was a two-span structure with transect size of 6000 mm × 2500 mm, and the buried depth of utility tunnel body was 2000 mm. Seismic responses of the utility tunnel system and the soil around it were simulated, and the response characteristics of the whole utility tunnel system were discussed. Results show that the strength of earthquake, the quality of soil, the buried depth, the system structure, the wall thickness, the amount and distribution of steel frame and so on have great effects on earthquake damage of utility tunnel systems.
