Support system load test of beam Bailey truss of Three Gorges Project ship lift

Wang Wenliang,Xiao Chuanyong,Zhang Junxia

Strategic Study of CAE 2013, Volume 15, Issue 9,   Pages 50-54

Abstract:

During the continued construction of Three Gorges Project ship lift, the loading test experiment has been carried out before the pouring work of the beam concrete, which is aimed at the complex characteristics of the bracing system of tower column beam construction. The experiment chose axle 1 beam, axle 2 beam and corresponding foundation beams' Bailey trusses as models, and the loading prototype test is conducted according to 1:1 ratio scale. Through arranging proper monitoring points and adopting reasonable testing frequency, the experiment completed the collection and analyzing of test data. The test results are as follows： The test obtaines the maximum stress of different member bars during the loading procedure. With the increasing of loading capacity, the bending variation of beams and Bailey trusses build up slowly, while altitudes of formwork and framed bent drop. With the increasing of loading capacity, the beams and foundation Bailey trusses experienced subtle side movements. The variation of both the axle 2 beam formwork and the framed bent's verticality from left to right is very tiny. The monitoring data indicates that, the parameters of strengthened Bailey trusses meet the safety requirements, and the proposal applies to the tower column beam construction while ensuring its safety.
