Simulation Analysis on Construction Control of Low Tower Cable-stayed Bridge

摘要

To ensure the construction quality, safety and reliability, according the design drawings, construction process and the related design code, this paper establishes the simulation model by the software of MIDAS/CIVIL for the analysis of construction control of the low tower cable-stayed bridge. The calculation results showed that the maximum cumulative horizontal displacement of the tower and vertical displacement of the beam is 13.8 mm and 154 mm respectively, which can be adjusted by setting camber. At completion state of the cable-stayed bridge, the stresses of the tower and the beam are both in compressive with the maximum of 14.47 MPa and 14.03 MPa respectively, which are both less than the limits of corresponding materials. The bridge is safe and reliable.
