The Padma Bridge Railway Link Project - Bangladesh
Type of Project :Reinforced retaining walls (RSWs)
Material: GGR/HDPE/US160、GGR/HDPE/US180
Date: 2018
Description:
The Padma Bridge Railway Link Project in Bangladesh represents a significant milestone in the country's ongoing infrastructure development, spanning approximately 170 km. This multipurpose bridge accommodates both rail and road traffic, operating at a speed of 120 km/h. The project includes a sub-grade foundation of 132.311 km, which accounts for 78% of the entire route. The rail link passes through densely populated areas where the sub-grade lacks adequate natural grading conditions. To address these challenges, the engineers at BOSTD implemented twin-sided tensioned geogrid-reinforced retaining walls (RSWs). This approach is a safe and cost-effective solution that enhances bearing capacity and resistance to differential settlement. The construction phase of the RSWs in the Padma Bridge Rail Link Project spans approximately 1.8 km, with a maximum wall height of 12.8 meters and a tendon spacing of 30 cm. BOSTD's engineers installed two types of high-strength polyethylene unidirectional geogrids (GGR/HDPE/US160 and GGR/HDPE/US180), totaling an impressive area of roughly 1.132 million square meters.
The construction of the Padma Bridge Rail Link was completed and officially opened to the public on December 24, 2024. This rail link dramatically reduces travel time between Dhaka and Jessore from ten hours to just three hours, significantly enhancing transportation efficiency and improving connectivity for Bangladesh and its neighboring countries.
