Discussion of Load Combination Parameters for Heavy-cargo Transportation in Passing Highway Bridge

摘要

To discuss about choosing the parameters of bearing capacity with over-size transport passing the bridge, this study analyzes the characteristics of designing load of heavy transportation which are different from the general cars; according to the characteristics of accidental load of heavy-cargo transportation, this research analyzes and proposes the load combination principle of heavy-cargo transportation load; discussions and recommendations have been made on the method of determining load bearing partial coefficients for calculation of over-size transport of highway bridges.
