Due to the economic , aesthetic advantages , cable-stayed bridge has become one of the most important bridge type of long-span bridges . The unique cable-stayed bridge after another, this cable-stayed bridge construction control problem is the main problem in the cable-stayed bridge construction . Small Ling Bridge engineering background , double arch tower cable-stayed bridge construction control of three key steps , the specific contents are as follows : (1) Small Ling Bridge Vertical Rotating the construction process , and use of space finite element model to simulate the entire vertical transfer process , different conditions from different angles arch tower forces and displacements calculated cable forces size to fully grasp the force of the arch tower , and actual vertical transfer process appear arch tower \(2) the unstressed length control method, calculated on the cable-stayed bridge flexible cable installation cable force . According to the actual situation of the cable tension program optimization, calculation and analysis of new tension programs , to fully grasp the cable through the installation process , to ensure the tensioning process in a safe and controlled state . Original tension program error analysis, and the actual process of tension deck load is influential to the installation of cable force is analyzed and calculated . (3) off the beam method of construction of large-span steel cable-stayed bridge control technology . Significant drop in the beam construction requirements, select the sand box as a temporary buttress , a multi-step hierarchical drop - down construction method drop for xiaoling Bridge beams . Construction controlling data according to the number of steps have been identified stars Step dips and each step of the drop- down amount , the equivalent gap element calculation method , the original calculation method has been optimized , the entire calculation process requires only one model is completed , the results Show the entire girder falling for the force security, the calculation is simple and practical . The development and application of the system to convert the drop- beam method of construction technology and gap elements method of calculating a reference value.
