Abstract

The main bridge of Cao Lanh Bridge is a double-pylon and double-cable-plane PC cable-stayed bridge with a main span of 350 m. The main edge beams were cast in situ with form-traveler by the method of asymmetrical double-cantilever, that was, the concrete casting and cable tension of the main span were prior to the side span during the construction of the symmetrical segments on the two sides of the cantilever. In order to study the structural characteristics and variation trend of alignment, the finite element model of the whole bridge was established by the software MIDAS Civil, and the parameters of concrete elastic modulus, shrinkage strain and form-traveler stiffness were modified during construction stages. The alignments of pylons and edge beams were controlled based on the analysis results of stresses, displacements and cable forces of construction stages. The results show that the alignments of pylons and edge beams in completed stage meet the requirements of specification and design.
