Abstract: Based on the purpose of the bridge health monitoring, a new health monitoring system, including hardware and software part, is proposed for cable-stayed bridges in detail. The system is categorized as five sub-systems covering sensor system, data acquisition system, data analysis system, simulation analysis system, and warning system. Many monitoring parameters including environment wind, temperature field, humidity field, strain, deflection, cable forces, and traffic can be obtained by those five sub-systems. The purpose and monitoring content of each parameter are illustrated in the paper, and moreover, the method of the layout of the measuring points is put forward.

Abstract: Based on the extensive research and analysis of actual condition of top culvert of high embankment, a calculation theory for the earth pressure of top culvert was presented. The theory could optimize the structure design for culverts, and reduce the waste of resource. First, based on the simplified assumption of the stress of soil on the top culvert and the analysis of single unit of the load on the top culvert, the calculation formula of earth pressure on different position of top culvert was presented by theoretical derivation. Then, to verified the results by using scaled test model and ABAQUS finite element software. Through the comparison with the traditional calculation theory and finite element simulation, we could prove that the calculation theory is more tallies with the actual situation of the earth pressure on the top culvert.
