This study analyzes the land subsidence caused by natural consolidation in the Thamrin Area, Central Jakarta, along the MRT CP201 tunnel route. Jakarta’s soft soils, particularly clay layers, contribute to land subsidence, with 0.2 to 3.6 meters and rate of subsidence is 1,24 cm/years. Using both analytical (one-dimensional consolidation) and numerical (finite element) methods, subsidence predictions were made based on geotechnical data from three boreholes which is TS-01,TS-02 and TS-03. Results show positive correlation between the two methods, with numerical approach yielding slightly smaller values due to its consideration of both vertical and horizontal deformations. This analysis highlights unavoidable nature of subsidence due to natural consolidation and emphasizes the need for mitigation and adaptation measures, such as spatial planning and monitoring systems, to minimize impacts on infrastructure.
