The appearance of the suspension bridge , although the United States , but its construction process relative to other bridge type is more complex , involving many issues . The suspension bridge main components include : bridge towers , main cables , slings, stiffening girders and anchor pier . Its construction process is the most complex , the construction process , including empty erection saddle pre- biased with pushing and lifting of the main beam , cable clamp stakeout , wind the cable tension and other crucial links . The construction of these links is directly related to the force of the main tower and full-bridge into a bridge linear , even the decision can eventually meet the design requirements , to complete construction goals . Control of the construction process , the suspension bridge is also extremely important . In this paper, the actual engineering Sichuan gas East a suspension bridge pipeline project as background relying , through the creation of the finite element model , the simulation of the construction process , site data collection and processing and analysis , its key link in the construction process , including cable clamp stakeout The main saddle the pushers and pipeline construction and other key construction step control and research . And the solution of practical problems arising in engineering , mainly to the following conclusions : 1. The main saddle pushers process in-depth analysis , considering the actual situation on-site construction , and new issues arising , the main saddle top push the program has been optimized to facilitate on-site construction while ensuring the main tower of the displacement and stress in the specification allows the range of class ; pipeline construction process may cause structural members security issues in the software simulation and calculation on the basis of concerned about the pipeline construction process piping overturning the important question of the possibility of bearing security , as well as linear , practical engineering advice for problems that may arise and ensure site safety in the construction process , but also conducive to the smooth completion of the monitoring work .
