Separate Single Column Pier Of Continuous Girder Bridge Offset Diseases And Strengthening Methods Research

Along with the rapid development of highway bridge construction,bridge accounted for a larger proportion in the highway Bridges,the quantity is increasing.Girder bridge lower part of upper structure domain structure through the bearing connection,bearing in the process of construction and operation is susceptible to disease,the upper structure will be vertical or horizontal offset.Bridge pier by the level of lateral pressure on both sides of the soil stress imbalance,construction of bridge pier local thrust and the level of the upper structure of bridge pier thrust pier tilt.Common correction methods are in place temporary steel structure construction,pusher in place again.In this paper,we study the lateral deviation rectification technology of bridge structure construction new technology,is the direct use of the beam of the abutment and pier component body action,overcome traditional construction time is long,the shortcomings of low efficiency,high cost,and that at the same time,hence the highway within sichuan,chongqing highway along the river,guangdong mei big highway,zhaoqing YueGui application in highway bridge construction and won.The construction technology innovation in the future maintenance of highway bridge construction has great use and popularization value.Past research more concentrated in the horizontal or vertical partial adjustment of space,yet few studies diseases.it and overall adjustment of all sorts of attitude.Obviously,to carry out the overall bridge components after adjustment and cause analysis design method of all sorts of attitude of study,to improve the level of bridge structure construction,avoid early gesture of bridge structure during the construction of the components damage,ensure the service life of the bridge,has important economic and technical significance.At the same time,the lower part of upper structure domain structure of the bridge through the bearing connection,bearing in operation process is prone to disease,bridge under the influence of various factors in operation,and abnormal posture space bridge components,in order to guarantee the normal operation of the Bridges,maintenance and construction requirements of higher technical level,this paper studies the bridge superstructure lateral deviation rectification technology construction of the new techniques,abnormal posture adjustment for bridge components construction design,construction technology and control technology development also has a direct role in promoting,at the same time in the custody of the bridge component maintenance theory and the development also has important academic value and broadapplication prospects.
