| Abstract: | The paper establishes the optimum module of cables of cable stayed bridge with low pylon on the basis of cable stayed bridge cable force influence matrix and taking the structure strain energy to minimum as the objective function. It also makes the optimum analysis for cable force in the combination with Xiaoxihu Huanghe River Bridge in Lanzhou City so as to get some conclusions with a certain value for reference. |
