小半径曲线箱梁独柱墩匝道桥荷载试验研究

通过对某小半径曲线箱梁独柱墩匝道桥进行空间梁单元、实体单元有限元计算与荷载试验,了解该桥型在不同的支座预偏载条件下、内外偏载、扭转荷载作用下的结构应变、独柱墩处的扭转位移、侧向位移等结构行为特点,为结构的设计、施工、结构运营检测提供了依据.

Load Test Study of Small Radius Curved Box Girder Single Column Pier Ramp Bridge

The bridge type in the bearing pre-partial load conditions, internal and external partial load, reversing the structural loadsstrain, Single Column Pier at reversing the displcement, lateral displacement characteristics of the structural behavior were learned through calculation of the solid elements and the load test of Space Single Column Pier Ramp Bridge on a small radius curved box beam, which provides basis for structural design, con- struction, structural operations detection.
