Research conclusions: The monorail adopted in the Phase I of Jiaoxin Line of Chongqing light rail was the first time for China to use it．The structure of the used T—shaped pier Was reasonable，which adapted to the characteristics of monorail pressure．The selected loading met the requirements of the various construction conditions and service condition for monorail．The precise design of the parameters for bearing pad—stone not only met the construction requirement，but also broke through the Japanese monorail construction mode that the pier Was constructed first and the beam is constructed late．
