The Structural Force And Safety Analysis Of The Wuhezhuang Bridge

Since the 1990 s,China's bridge industry has developed rapidly and has become an important pillar of economic growth.However,the bridge industry,the bridge structure itself has been the safety of the constraints of the development of the industry focus,the bridge structure in the construction of the security issues of the construction unit has been in the research and development.At present,there are many hidden dangers and problems in the safety of bridge industry in China.These safety problems have caused damage to the construction workers and their families and construction units,and have the resistance to the development of the bridge industry.Therefore,the safety analysis of the bridge construction process is needed.This paper first according to the basic conditions of the Wuhezhuang Bridge,through large structure finite element analysis software Midas civil model,static model,analysis the stress and displacement of the bridge,and to design the PSC,calculating the Bridges in new specification "highway bridge design general specification"(JTG D60-2015)lane loads whether meet the specification requirements.Secondly,the displacement and stress state of the main girder in each construction stage are obtained by modeling,and the measured data are obtained by field detection.The measured data are compared with the theoretical data,and the Wuhezhuang Bridge is carried out.Safety analysis.Finally,the seismic analysis of the Wuhezhuang Bridge is carried out through modeling,and the seismic safety evaluation of the structure is carried out,and the influence of relevant parameters on the seismic response of the structure is studied.
