| With the development of the city, many kinds of special reinforcement concrete structure come into being, to satisfy the multi-function and beauty of the buildings. During the construction, grate span and height of the scaffold and kinds of loads on the concrete structure bring forward many higher demands to the design of the scaffold.In the recent years, there is a grate advancement on the mould plate and the scaffold, but in the whole, there still is a grate gap on the technology and management with the aboard. In 1994, building department noted that the new type of mould plate and the scaffold should be applied. But there is no according code. In recent years, there were many accidents, because of the laggard marketing and management system. And lack of the understanding in the building company, the mould plate and the scaffold are not calculated carefully, and the strength and stability of the bracing system are not enough.Based on lots of investigation and materials, this paper analyses the bracing system of the trestle bridge, choose the bowl-shape-fastener as the bracing material, use ANSYS to establish the space 3D model of the bracing system, simulate the performance of the bracing system, analyze the affects of the sedimentation of the bearer and the bracing system to the bearing capacity, and discusses the calculation of the bracing system, materials and the profession of the scaffold. And this paper also compares the bracing system in this paper with several actual models to offer clews to the bracing system of special structure. And in the end, this paper discusses the development of the scaffold system, including the new materials' application, the specialization of the building group and etc.There is no according code and standard for the scaffold, so, the analysis in this paper provides reference for the construction, which reduces the hidden danger, improves the safety, advances the project quality, shortens the time, and reduces the cost.
