The Monitoring Research of Stress and Displacement about Arch Framework with Flush Joint Precast

Abstract:

The entity model of slope arch framework in highway was monitored in stress and displacement at different time. Though the date of different points collected, the mechanical mechanism can be studied, and the analysis was done between calculation results and entity model. The studying results show that the stress of point were increasing at first and then mitigating, and the stress increase undulating as the distance from the slope top increase. The date of monitor and finite element analysis model indicate that the point on the arch toe is the worst stress place, and the total displacement increase nonlinear as the distance from the slope top increases, and the bump phenomenon exists in the bottom of slope, the points are likely to be broken.
