The Related Technology Research And Analysis Of Continuous Rigid Frame Bridge

In the 21st century's first decade with China's raPid economic development. On this basis, the traffic demand in China has also been a leaP in development. This makes the construction of highway in the early defects gradually revealed, the most serious is the highway traffic flow can hardly satisfy the needs of today's traffic. Much-needed widening of the highway reconstruction. Road traffic in the bridge as an imPortant Part of the bridge reconstruction is an imPortant Part of highway reconstruction development. This makes the construction of highway in the early defects gradually revealed; the most serious is the highway traffic flow can hardly satisfy the needs of today's traffic. Much-needed widening of the highway reconstruction. Road traffic in the bridge as an imPortant Part of the bridge reconstruction is an imPortant Part of highway reconstruction.In this PaPer, the Beijing-Zhuhai ExPressway Luohe Interchange, for examPle, the continuous rigid frame bridge reconstruction in-dePth research. Following major elements:(1) Finite element software, respectively, before the establishment of widening the bridge and widen the way the different bridge widened the sPace finite element model, weight and live loads from the bridge such as widening of the continuous rigid frame bridge after bridge safety and bridge oPeration safety implications of Factor in starting, respectively, two different connections on the bridge widened the static and dynamic Performance analysis and comParison of reconstruction after the above factors influence the structure of the bridge, and made a bridge design and construction of the ProPosed widening.(2) By simulating the three different deposition conditions, and the three conditions were calculated in two different ways of widening the bridge structure changes. Summed uP the way of two bridges rebuilt settlement control indicators and methods to eliminate differential settlement.(3) Widening of the bridge considering the creeP Performance, the continuous rigid frame bridge deflection under its own weight, and Prestressed arch under the variation of the anti-A finite element simulation and calculate the results.Through this study, can be summed uP in different continuous rigid frame bridge widening with the features. Widening of the bridge for a similar reference...
