| The bridges constucted in early days became "bottleneck" of the highway transportation, because it's standard were low and shortage of load capacity, they have unsuitable for present reality of great volume of traffic and the heavy load vehicleserious, the massive existences of critically ill bridge havehindered the transportation to be unimpeded. All reconstructions are uneconomical and not scientific, So the old bridges' reinforcement and maintain then seem to be increasingly important. And how to examine the result of reinforcing correspond to become a carely topic of road margin.The bridge traverse condition involves beam's load traverse distribution, it's test is one of the important method of appraises the bridge condition. The load traverse distribution coefficient calculation is a medium important contents in the design of highway and bridge. Make use of internal force or load traverse distribution coefficient to analysis bridge structure, substantially is within the scope of certain error margin to look for an influence noodles for looking like to replace accurate influence noodles, make the space structure converting into the flat surface problem of internal force calculation's problem to resolve reasonably.This text discuss the reinforces mechanism and technique about the old bridge first. Then mainly carry on a research for the load traverse distribute theories, through the loading experiment, make use of the load traverse distribute theories research on actual engineering. This part mainly combine with the Ku Er Le Kong Que He bridge's static loading experiment around reinforcement, measure the bridge's medium acrossed Moves and contingency in the load function. Through compared with the caculation solution, get each value's checking coefficient. Then get the bridge's working condition coefficient in that loading grade, attain the bridge condition appraisal in extreme limit force or normal usage appearance.While concretely computing, using FORTRAN language making procedure on Hinged Slab method about the load traverse distribution coefficient, this can solve the problem of great caculation from computer. |
