To improve its anti-seismic capacity, the paper studies the performance characteristics of utility tunnel system under seismic loads based on a shaking-table experiment. Herein, two models of two-span UT with rectangular section are set up, one is used to simulate the main utility tunnel, and the other is for branch utility tunnel. Three kinds of pipeline are installed in UT to model the water-supply system, cable and power-line system respectively. This research is used to identify and explore seismic performance of utility tunnel body and its inner pipeline. Anti-seismic performance of pipeline abutment and joints based on passive control device is also experimented to check their capacity of resisting earthquake damage. The experiment is done on the 3m X 3 m shaking-table; three selected seismic records are input. UT model with the scale of 1: 10 is built up based on statistics of the popular utilities system in China. Based on experiment results, a theoretical theory and simulation on the platform of ANSYS is done, some valuable conclusions have been got. The results had show that buried depth, wall thickness, steel amount and its distribution, and earthquake motion parameters have a big effect on earthquake damage of utility. These pipeline, cable and support contained in utility are also vulnerable to the earthquake in certain conditions.
