Research On The Optimization Of Eastern Extension Of Electricity Projects On The 2nd Line Presponse To Duration Reduction

In this paper through the analysis for Shanghai Rail Transit development status and the east extended catenary construction of the 2nd line on Shanghai Rail Transit status and existing problems we discussed the nedd for reform to the construction program because of the short time and heavy workload. According to Shanghai Shentong Group (building side) demand, we made Reasonable Construction Program which can solve the short time and heavy workload problem of this project. When we optimize the construction program, we mainly reference to the concepts of national urban rail transit construction of catenary and requirements of Shanghai goverment on the east extended catenary construction of the 2nd line on Shanghai Rail Transit, and according to safety and reliability of the catenary, we developed the initial catenary construction plan of this project. At last through the analysis of the Reality of the project we worked out a scientific and rational optimization of the project.
