Abstract: Beijing Workers Stadium project because of the large area foundation pit and tight construction period, relying onthe tower crane for materials completely does not meet the schedule requirements. A steel trestle was designed fortransportation and construction vehicles, which was convenient for material transportation and construction and speeded upconstruction speed. The whole installation process of steel trestle was introduced. The finite element simulation of theinstallation process was carried out by MIDAS Gen software to ensure the safety of steel trestle. The health monitoringsystem of steel trestle was established to carry out load test and ensure the reliability of trestle project in service period. Theresults show that the steel trestle is safe and reliable in the installation process and service period, the steel trestle caneffectively resist the reciprocating load of vehicles.

Keywords:Beijing Workers Stadium; steel trestle; load test; finite element simulation; large height difference; heavy load
