吊杆张拉控制力的确定是系杆拱桥施工过程中的关键问题,也是一个难点。针对这个问题,文章提出一种循环迭代方法,采用ANSYS建模,用降温的方法模拟吊杆张拉,同时利用APDL语言编制了相应程序,用以求解吊杆施工张拉控制力。通过在马鞍山市采东桥施工中的应用,证明了这种方法的正确性和实用性。同时,计算表明,即使对于较高的精度要求,该迭代方法仍具有较好的收敛性。 It is also a difficult point to determine the control force of the boom tensioning, which is the key problem in the construction process of the tie rod arch bridge. In order to solve this problem, this paper proposes a cyclic iteration method, which uses ANSYS modeling to simulate boom tensioning with cooling method. At the same time, APDL programming language is used to solve the tension control of boom construction. Through the application of the construction of the mining bridge in Ma’anshan City, the correctness and practicability of this method are proved. At the same time, the calculation shows that the iterative method has good convergence even for high precision requirements.
