| Abstract | Land subsidence has been an issue in Bangkok, Thailand, and continues to be a problem nowadays. In Bangkok Subsoil, some construction site areas are located near the river and canal. The high subsidence in the research area occurs at a rate of approximately 20 cm per year in the construction site area, which is close to the river. The research needs to find out that the river variation affects the high subsidence or not. If it affects, this research is to propose the project owner of the construction site for installing the monitoring system near the river. The subsidence model of the construction site due to the river level variation is set up in order to expose the cause of high subsidence failure. The different river level variation scenarios are conducted because of the lack of a monitoring system of the river for the subsidence modeling. In this research study, a fully coupled flow deformation simulation of Plaxis 3D is carried out for the ground subsidence assessment due to the river level variation. Based on the validation results from subsidence analysis, the high subsidence has occurred because the water was drawdown and passed through the loose to the medium sand layer where is the porous media material. The high subsidence is caused due to the compression of the loose to medium sand layer. |
