CALCULATION OF THE DRAFT OF THE FLOATING BRIDGE BUILT FROM PLASTIC BUOYS WHEN THE LOAD IS A TRUCK

In some emergency traffic situations such as rescue, natural disasters... it is necessary to build a temporary bridge to cross the river. Using a quick-assembled floating bridge made of plastic buoys is the appropriate solution. This article presents the study of calculating the draft of continuous floating bridge assembled from plastic buoys. The author calculates the draft by two different methods, which are theoretical calculation and finite element modeling using SAP2000 software, to verify the discrepancy of the results of these two methods. The results obtained show that the discrepancy between these two methods is insignificant, and continuous floating bridge assembled with a layer of plastic buoys can withstand a small truck load of up to 12.3 tons.
