Rhombus Cradle System Checking Computation of Jinqinggang Bridge

摘要：

　　In order to be sure the safety of rhombus cradle system during the concretes cantilever cast-in-place construction,the paper makes use ofprobabilistic limit state method,and carries out the checking computation.According to the rhombus cradle design drawings of the Jinqinggang bridge and the actual load case,the analytical model is founded through the finite element analysis software MIDAS/CIVIL The results show that stress of all parts of the rhombus cradle system and the concrete local pressure stress is less than the corresponding material design value,and the safety factor of anchor rod tensile stress is less than 2.0 which should be strengthened,and the deformation of the steel moulding plate is less than 20mm.
