| Abstract: | The key point of determining rational completion state of cable-stayed bridge lies in how to control the cable forces when completing cable-stayed bridge.On the basis of document at home and abroad, the advantages and disadvantages of related research fruits are compared and commented.Thus it is put forward to adopt synthetical rigidity cable method and automatic adjustmentmethod of cable forces to ascertain the principles and steps of determining the cable forces.One instance indicates that the concepts are explicit and the calculations are convenient in this method.Furthermore the results meets the request. |
