| Abstract: | On the basis of the project of western valley 1# super major bridge on Chongqing-Guiyang expressway,set forth are the application of cradle technology in cast-in-place cantilever construction of concrete beam bridges.A survey is presented of the structure,design calculations and static load tests of the cradle.Built up is the finite element model of the cradle,with which simulated are its stresses and deformations in construction and operation,thus providing reliability basis for construction control. |
