Research On Force Performance And Linear Control Of Triangle Hanging Basket Of (32+48+32)m Continuous Beam Bridge

With the continuous development of society,China has gradually built infrastructure as an important goal of today's social and economic development tasks,while the state has also strengthened the foundation for the construction of financial support and policy support.The construction of the bridge engineering as an important part of construction industry in our country,not only has a positive impact on China's transportation industry development,but also made great contributions to the development of city construction in China.Based on the analysis of large span continuous beam cantilever construction hanging basket stress performance,discussed the current commonly used in engineering triangle hanging basket construction process and mechanical performance,and discusses the continuous linear control of cantilever construction,summarized the influence of hanging basket construction technology of bridge engineering.This paper is divided into five chapters,first of all,the current status of the bridge project in China is briefly introduced and some of the main bridge.Secondly,the most widely applied the triangle hanging basket is analyzed in detail in the bridge engineering,and the Beijing Shijiazhuang Passenger Dedicated Railway line across the Lugou Bridge Road(32+48+32)engineering practice m bridge in the triangle hanging basket as the research object,MIDAS modeling and stress analysis of mechanical characteristics of triangle hanging basket and to summarize,provides some engineering data to study the stress performance of similar triangle hanging basket.Again,the linear control of large span continuous beam construction is discussed.Linear monitoring is divided into measurement construction process design and construction stage monitoring of two parts,by comparing the design of linear change of the measured and calculated values of the influence of different parameters,the error correction in the construction process on the bridge alignment change,to ensure that after the completion of construction of the main bridge structure stress and linear meet the requirements.Finally,through the research above in engineering practice,for the future construction of domestic large span continuous beam bridge construction is the most widely used triangle beam hanging basket,put forward the matters needing attention in construction and construction practice and related data to give constructive suggestions.In this paper,through the construction of large span continuous beam cantilever construction triangle hanging basket of the force performance and its linear monitoring of the study,as a bridge construction project in China to provide more advanced theoretical support.
