Applied Analysis of Traffic-keeping Measure in Reconstruction and Expansion of Highway:The Construction of Cast-in-Situ Box Girder of Shangqiu-Zhoukou Highway across Ji'nan-Guangzhou Highway

In this paper,based on construction process of overhead cast-in-situ box girder of Shangqiu-Zhoukou highway across Ji'nan-Guangzhou highway,the contradiction between the construction and traffic in maintenance and reconstruction and extension construction of highway is made in-depth analysis and discussion,effective traffic-keeping measures of ensuring the coordination between highway construction and vehicular traffic are summarized,so as to propose a practical solution to ensure the smooth in reconstruction and extension construction of China's highway.The solution has strong applicability,which can provide reference for highway engineering construction carried out in a large area in our country.
