UNDERSTANDING HOW INFRASTRUCTURE INTERACT WITH THE RECLAIMED LANDS HAVING EARTHQUAKE INDUCED LIQUEFACTION VULNERABILITY

The paper aims at evaluating the interaction between infrastructure like bridges, buildings, slopes, roads, and foundation with reclaimed land with earthquake induced liquefaction vulnerability. The assessment begins by providing an overview of the study topic by introducing the areas under study and giving its background information. The researcher carried out a secondary data through the analysis of the existing information on the interaction between infrastructure like bridges, buildings, slopes, roads, and foundation with reclaimed land with earthquake induced liquefaction vulnerability. The primary data collection method used was interviewing, and the chosen area of study was the Northeastern part of Bangladesh with a focus on Sylhet and Mouluvibazar. Observation and photographing were also used a primary data collection method. Tests were also carried out by the use of Cone Penetrator Tests (CPTs) to offer data for soil types and soil layers. The finding of the study was that lateral spreading of the soil around the liquefaction lines, slopes, and areas where the arrangements apply pressure. The other result was that fissuring on the ground surface causes railroads and tarmac roads to break. From the study outcome, it was concluded that structures erected on reclaimed lands that have earthquake-induced liquefaction vulnerability are at risk of being destroyed at any time in case of lack of a
