The Construction Schemes And Controlling Technology Of Wenzhouliao Bridge (a Continuous Rigid-frame Bridge) Of Qingjingqing Highway In Zhejiang Province

As a light bridge, a Continuous rigid-frame bridge is a new type of bridges suitable for loess and gully areas. Because of its beautiful structure, its sustaining force well as well as its offering a comfortable environment for driving, such a kind of bridges has been often built since 1990. Simultaneously large span continuous prestressed concrete continuous girder bridge construction have morn and more application for the cantilever casting method, its advantages is in creasingly obvious, but along with its span unceasingly increasing, the construction control request is higher, the construction control difficulty is more and more big , a series of problems in the construction control have came about. This thesis ,first of all, introduces the advantages of continuous rigid-frame bridges as well as the characteristics of the structures and the force sustaining of the continuous system of continuous rigid-frame bridges. At the same time, it explains the construction methods of such bridges,too. Taking Wenzhouliao Bridge of Qingjingqing Highway in Zhejiang province for example, it elaborates the general conditions of Wenzhouliao Bridge. It also makes detailed introduction of the construction schemes and the controlling technology applied the lower and upper parts of the bridge as well as the monitoring methods applied to the construction of the upper part of the bridge. Therefore, by analysing and summarizing the above concrete instance, the thesis is of value for reference.
