| Abstract: | Based on the project of a rigid-frame and cable-stayed composite bridge,the principles and methods for the construction monitoring of this kind of projects are proposed.And a three-dimensional space finite element model is built to simulate and study the whole process of the construction.This paper also emphatically introduces a field measurement scheme,and compares and analyzes the calculated value with the field measured results.The practical research indicates that the monitoring procedure and technique measures employed in the monitoring process are highly practical and can provide reference for the construction of composite bridges of this kind. |
