Abstract

The paper presents a practical solution for upgrading the basement depth of a high-rise building in Ho Chi Minh (HCM)
City, Vietnam. Finite element analysis, Plaxis 2D, was employed to simulate the construction site with two different kinds of walls, namely the diaphragm walls (DW) and the secant piles walls (SPW). In the project, SPW was installed next to the existing DW from the basement line, and further deep excavation could be proceeded . FEA results of the lateral deformation of DW and SPW as well as the ground surface settlement were compared with field observations. The comparison shows a good agreement between the numerical work and the field monitoring data. The overlapping lengths between two types of the wall were also investigated for design optimization. The current study can be used for future design projects under similar scenario.
