Abstract
The project finished the construction of diaphragm wall ten years ago. Due to change of the Owner, the scale of building was increased, higher and deeper. Therefore, an additional diaphragm wall, beside the existing one, was considered as a solution for basements structure. This paper aims at giving a case study on calculation method of two parallel diaphragms walls system, which be called double diaphragm wall, based on inhouse software with finite difference method and Plaxis software with finite element method. The deflections, bending moments and shear forces came from two methods were relatively similar and reasonable. This paper also presents some challenges on the construction experience during constructing the additional diaphragm wall on site. Some conclusions will be drawn for design and construction, as a referential case for future projects.
