Analysis And Reinforcement Technology Of Bearing Capacity On T Type Rigid Frame Bridge

Nowadays the transportation develops fast,the maintenance of the established trafficroad has become a point which can not be ignored. Bridge plays an important role in thetraffic.The T type rigid frame bridge is a common structure in bridge building, while it isbroadly designed in all ranks of highway.Related to the characters and constuctionfactors,the concrete of the T type rigid frame bridge became crazing ever since when it isused,some fissure appeared in the bottom of the bridge beam.The fissure became larger andlarger when the bridge was used to provide routeway for people and cars,it creatednegative influence to the structure.So the detection and reinforcement should be studied asan important issue.In this paper, it do a research in the carrying capacity of bridge and the renforcementtechnology of T type rigid frame bridge. The research focuses on practical engineering inShizuishan road which depends on the analysis programme,and it gives the internal forcestudying of the bridge.The data of the bridge by detection was a direction of the twodifferent methods for reinforcing the bridge,as it supplied the evaluation of the bridgereinforced.Under the comparision of the two way,they both could content the require ofstrengthen the bridge.What’s more,through deeper analyzing, the more excellent projectcame,Setting up steel reinforced concrete truss in the bridge structure can be a moreeffective way to increase its bearing capacity.In this article, it provides the test data obtained by the Yellow River Bridge ofShizuishan, the data were aimed at the original and the strengthened T type rigid framebridge, through the analysis of the data which were related to the bridge carrying capacityanalysis results, some feasible solutions were given to reinforce the bridge. At the sametime, the simulation of the bridge strengthened internal force state supported a furtheranalysis and evaluation of the bridge. then based on the analysis and evaluations,the moreexcellent reinforcing projects were obtained,the main factor of judging which project isbetter included cantilever bend,positive stress of up-edge and down-edge,main tensilestress,main crushing stress etc.The dissertation provided a reference for the bearing capacity analysis and reinforcement of the similar bridge.
