Penggunaan Geocell Sebagai Stabilisasi Tanah Dasar Yang Lunak Pada Proyek Pembangunan Infrastruktur Jalan Untuk Konektivitas Menuju Ibu Kota Negara (IKN)

Abstract

The effectiveness of using geocells as a method of stabilizing soft soil in the road construction project to the National Capital City (IKN), most of which is peat with low bearing capacity and is susceptible to subsidence and freezing. Geocells are geosynthetic materials in the form of three-dimensional cellular structures that can strengthen the soil by distributing the load evenly and resisting soil movement. This study examines the working mechanism of geocells, the characteristics of soft soil, and the application of geocells in increasing the strength, stability, and service life of road infrastructure. The research methods include literature observation, analysis of physical- mechanical parameters of soil and geocells, and evaluation of the performance of the base layer of the road reinforced with geocells through case studies and field data. The results show that the use of geocells can increase the structural stiffness of the base layer, reduce land subsidence significantly, and allow a reduction in the thickness of the granular layer by up to 50%, thereb reducing construction costs and accelerating implementation time. The Effectiveness of Using Geocells as a Soft Soil Stabilization Method in Road Construction Projects to the National Capital City (IKN) Much of the land along the road network to the National Capital City (IKN) consists of peat soil with low bearing capacity, making it highly susceptible to subsidence and instability. Geocells, which are geosynthetic materials in the form of three-dimensional cellular structures, can enhance soil performance by distributing loads evenly and resisting soil movement. This study examines the working mechanism of geocells, the characteristics of soft soils, and the application of geocells in improving the strength, stability, and service life of road infrastructure. The research methods include literature review, analysis of the physical–mechanical parameters of soils and geocells, as well as evaluation of geocell-reinforced road base layers through case studies and field data. The results indicate that the use of geocells significantly increases the structural stiffness of the base layer, substantially reduces land subsidence, and enables a reduction in the thickness of the granular layer by up to 50%. Consequently, this method reduces construction costs and shortens project implementation time.
