Model Test on Incremental Launching Construction Method for JIUBAO Bridge in Hangzhou
The incremental launching construction method of super large-span arch-girder combination bridges is a new way in construction for late-model bridges.In order to study the dangerous conditions during the construction of the real bridge, the similarity model of a large-span arch-girder combination bridge is introduced.This article discussed structure responses under one, two, three times dead-load additional weight and the wind load separately.The test result demonstrates that the test method could simulate the dangerous conditions during the real construction and check the stress effectively which can provide technical support for the construction of similar bridges.
