Passenger line along the support and foundation design and construction process
Abstract：The design of the passenger line along by supporting and foundation treatment for analysis, the slope of the supporting structure along the railway, the railway passenger line embankments, ground handling, inspection roadbed stability calculation, the settlement after estimated slope revetment embankment, embankment design and construction programs. According to the special passenger railway design specifications, design lane roadbed embankment design, using gravity and pile retaining wall design calculations plate two embankments, as well as the settlement requires the use of sod to the slope of the slope, it is working to meet the passenger line after the treatment, and economic and technical comparison, designed CFG piles and two cement mixing pile foundation treatment program, and finally on the embankment embankment fill, slope and other construction design. This design engineers to achieve the purpose of basic skills training for careers in engineering design, construction of initial training to better train our ability to use industry standards as well as the ability to use computer-aided analysis and design.
