Construction Control and Simulation Analysis of Long-Span Cable-stayed Bridge Fangwen WU1,a, Chengfeng XUE2,b 1 Associate Professor, Faculty of School of Highway, Chan’An University, Xi’an, China 2 School of Civil Engineering and Architecture, Southwest University of Science and Technology , Mianyang, China awufangwen2004@163.com, bChfxue2008@163.com Keywords: Bridge Engineering ; Cable-stayed Bridge ; Construction Control ; Forward Calculation Method; Backward Calculation Method; Unstressed State Control Method Abstract: Simulation analysis is the basis for construction control of cable-stayed bridges, it monitors the process of the bridge construction.
The conditions such as elastic modulus of the material, component weight, concrete shrinkage and creep, temperature changes and temporary construction loads are difference from the actual construction parameters.

Theoretical analysis, numerical simulation and field rainfall experiment and indoor artificial rainfall test methods have been applied to study the fundamental mechanism and process of rainfall infiltration induced landslides currently.Field test consume large manpower, material and financial resources, test period is too long, while the indoor artificial rainfall test combines the advantages of unit test and field test,which become a powerful tool for further study of the response rule of the unsaturated soil slope under rainfall conditions.
