Discussions on the Key Technologies of Construction of High Pier with Variable Section under Strong Wind
The pier of MORAČICA Bridge adopts the form of variable cross section of one limb-two limbs,and the highest of which is 161m.In this project,the construction technology of hydraulic self-climbing formwork is applied.The Moracica Bridge is located in a grand canyon where is a wind channel and with great wind all the year round,especially in the winter and spring season,the wind can reach force 7-8 level even up to 11 gale.Therefore,the effect of wind on the hydraulic self-climbing form work technology should be considered during the construction of the pier.In the paper,relying on the construction of pier of Moracica Bridge in Montenegro North-South Highway Project,the key technical measures adopted in the construction of high pier in severe wind environment are discussed.
