Monitoring and Analysis of Pre-compaction Tests with Up-going SX64 /2700 Movable-supported Bridge-building Machine

In order to ensure the bridge construction quality and safety,pre-compaction tests must be conducted before first use of movable-supported bridge-building equipment. Based on Hanjiang extra-long bridge on Xi'an- Chengdu passenger dedicated line,this paper introduces the finite element analysis the arrangement of measuring points, monitoring method and frequencies of the pre-compaction tests conducted with up-going SX64 /2700 movable-supported bridge-building machine. The elastic deformation and inelastic deformation are calculated and the stress testing data are obtained by means of monitoring the procedure of pre-compaction and analyzing the monitoring data,which demonstrates that the up-going SX64 /2700 movable-supported bridge-building machine meets the construction requirements of this bridge.
