Liquefaction on the design and construction of land-based passenger dedicated railway embankment
Abstract：The graduation project is through the analysis of the land-based liquefaction passenger dedicated railway embankment, slope supporting the completion of railway design, railway passenger line embankment design, slope design foundation treatment design, roadbed stability seized count, embankment slope embankment construction program and other designs. According to the special passenger railway design specifications, fully consider the characteristics of foundation engineering, design lane roadbed embankment design, using gravity retaining wall and slab pile retaining wall and then slope design, construction programs embankment embankment slope design. Through the analysis of the graduate design calculations, making me further strengthened the mastery and application of professional knowledge, but also to strengthen its own independent thinking and problem-solving ability to learn.
Keywords:Liquefied soil; Passenger Line; slope supporting structure design; foundation treatment; slope design
