Urban metro line No. 2 from An Suong station to Thu Thiem is one of the six metro lines that is planned to be built in Ho Chi Minh City (HCMC). The metro line goes through the area in which the stratigraphy consists of many units, distributed from 20-80 m. The hydrogeology mainly has 2 aquifers, namely Holocene, and Pleistocene which affecting the deep excavation. During construction, there will be some problems that will affect the work on the surface such as settlement, cracking, and damage. By finite element method on Plaxis software, the article forecasts the surface settlement during this metro line No.2. The results show that the ground settlement is relatively large in areas with soft ground structures. The settlement results depend on the geological structure characteristics, hydrogeological characteristics, and the shape and size of the tunnels
