| Abstract: | Long-span steel truss continuous girder bridge is a difficult problem in engineering design and construction because of its complex structure and high construction difficulty.Taking the construction of a long-span steel truss continuous girder bridge as the engineering background,this paper studies the stress state of the temporary support of the bridge by means of numerical simulation,and puts forward the construction precision control method in closure.Finally,the content and method of monitoring measurement in construction are studied from the perspective of construction monitoring measurement. |
