Abstract


Three tower cable-stayed - the self - anchored suspension continuous collaboration system bridge complex continuous collaboration system is a combination of the two cable-stayed - self - anchored suspension bridge with a single tower cable-stayed bridge , both the advantages of cable-stayed and suspension bridges , It has a sleek , firmness and flexibility . Characterized by force due to the self - anchored suspension system with a cable-stayed architecture , construction techniques, there is a big difference in the force is very complex, and there are many technical problems in the design and construction aspects , such as the overall structure of the highly nonlinear behavior of the tower and beam cable interaction coupling effects , the complexity of the process of the construction process , relying on the numerical simulation method does not adequately reflect the actual bridge force performance , not easy to find the problems in the process of bridge construction . Carry out such novel bridge model test research has important theoretical significance and practical value . Thesis project relying Hanzhong City West Second Ring Road Bridge , through the production of a 1:20 scale model to verify the feasibility of the theoretical calculation methods the correctness and construction process . First consider the self - anchored suspension - the non-linear characteristics of the cable-stayed combination system bridge , the simulation analysis based on the finite displacement method of relying on the whole process of construction , the various stages of the main cable , cable, boom , main beam , the main tower and Vice internal forces and displacements of the tower , with model test measurements to test the results of comparative analysis the boom tension on the mechanical behavior of the structural system and the performance of the force , space cable cable shape variation and the structure of the overall performance of the key technologies in the construction process . The analysis results show that the geometric nonlinearity of the bridge of the stage of the cable tension is very prominent ; the stage of the cable in tension unstressed length control-oriented , taking into account the needs of cable force ; system should be converted to the control cable force main , take into account the unstressed length of cable ; basically consistent with the measured values ??with the theoretical values ??of the model tests , the established theoretical model can simulate the actual structural stiffness , mass distribution and boundary conditions , based on this principle and method to establish the real bridge the finite element model can reflect the actual working conditions of the bridge , which can provide technical support for the design and construction of the bridge .
