Mechanical Performance Analysis of Side Wall Anchorage Zone of Long-span Cable-stayed Bridge Tower
This paper takes the anchorage zone of the main tower of the long-span cable-stayed bridge as the research object.Finite element model of anchorage zone of the tower was established by Midas FEA NX.The spatial stress of the anchorage zone of the tower was analyzed.The results showed:1)the transverse and longitudinal stress of the tower wall is compressive stress before and after the hanging cable,during the operation stage and under the condition of cable fracture.The prestressing tendon arrangement is safe and reasonable;2)the post-anchorage traction effect of the area directly above the anchorage tooth block of the long cable is more prominent.In the design process,the reinforcement in this area should be strengthened to limit its cracking.
