Application And Study Of The Construction Monitoring Technology On Hulan River Bridge Of Projection

With the increasing of the new building structures and the building size, the construction process will also become more complex,so the role of construction monitoring and control is more obviously.The role of construction monitoring and control is that use numerical simulation method to simulate the construction process of the structure in the computer, to solve the structure in all the construction phase of the internal forces and displacements.Comparing the theoretical and measured values to adjust a negative impact on the structure of the construction method to ensure that the structure in the construction process The security and reliability of the structure after completion of the process.This thesis will simulate the whole construction process of construction scheme in suspending construction, hydraulic synchronizing lifting technology, hydraulic synchronizing lifting and local jack-up technology. Consider form structural internal force distribution among the three schemes, suspending construction scheme is the best.and hydraulic synchronizing lifting technology and local Jack-up scheme followed. Proved that hydraulic synchronizing lifting technology and local Jack-up Scheme is better than hydraulic synchronizing lifting technology in internal force distribution and the bridge lineshape by constrast them for the bridge lineshape, structural closure precision, strength and stability checking of the bar. etc. Theoretically proved hydraulic synchronizing lifting technology and local Jack-up Scheme is feasible.Compared to the monitoring data and the theoretical calculations of local Jack-up process. And analysis the main reasons for differences between them. Verification that it is operational and feasible to use the numerical simulation method to simulate the mechanical behavior of construction process. At the same time, get some structure construction monitoring experience.
