Abstract A new pile-plank subgrade configuration was employed for the modern tram track project in Shanghai. Since the tram track is embedded in road pavements and the subgrade configuration is quite different from that of the existing urban roads，the long-term lateral differential settlement between the tram infrastructure and the road infrastructure is an inherent issue. To investigate the lateral differential settlement distribution between the tram infrastructure and the road infrastructure，which are considered as a comprehensive research object in this study，some centrifugal model tests in different cases were undertaken，and the influence of soil stress history，track location and load distribution on the subgrade lateral differential settlement was investigated. Test results show that the soil stress history plays a significant role in effecting differential settlement distributions. The settlement of the tram foundation develops most rapidly in the initial 6 months of the operation，and then，the settlement rate decreases gradually with the operation time. The settlement of foundation soil decreases with the depth and the settlement influence depth beneath the pile bottom is about 4 m. Basically，the most serious case of the lateral settlement appears when the tram track locates by the side of the urban road. The maximum lateral differential settlement rate in the transition zone between tram and road infrastructures is up to 4.37‰，and the value of the tram system is up to 2.42‰. Consequently，some transition zone reinforcements are required.

Key words： soil mechanics tram track pile-plank subgrade centrifuge model tests lateral differential settlement transition zone
