摘要：

To permit calculation of the power transmission capacity of cables carried in bridge ducts, methods for calculating the thermal resistance and capacity of a bridge, and changes in transient temperature of cables in bridge ducts are proposed. The validity of these methods has been confirmed by tests on bridges. It is also found that the heat trapped in the duct can be estimated by a convection computation taking radiation into due consideration.
