1. Project Overview
Taipinghu Bridge is located in Tongling-Tangkou section of G3 Beijing-Taipei Expressway, crossing the Taiping Lake in Mount Huang. It is a half-through, basket-shaped arch bridge of steel tubes with the layout of 4×20m+352m+3×20m. For the main arch rib, the space variable cross-section truss composite system is adopted, for the axis line of bearing arch, catenary alignment adopted, and the two arch ribs leaning to the bridge axis side in the vertical plane produce a basket-shaped arch. The central span between two arch feet is 336m, the vector height is 68m, and its whole span ranks first in Asia among bridges of the same kind. This bridge has become both a new representative in Anhui Province to promote the “Two Mounts and One Lake” scenic spot and a modern landmark leading the visitors to the spot.
2. Technical Features and Innovative Points
