Taking an interchange ramp bridge reconstruction project for example,through heighten the piers and remould-designing of the bridge bent cap,analysis of construction diffficuhies,and theoretical calculation of structure system transformation, a reasonable design scheme was proposed. Combined with the construction practices and monitoring measurement,it indicated the design proposal and construction craft are safe and reliable.
