Zheng west high speed rail foundation treatment and embankment design
Abstract:   The topic of this design is zheng west high speed rail foundation treatment and embankment design. In foundation treatment, mainly chooses the CFG pile composite foundation bearing capacity calculation, selection of pile diameter is 400 mm, determine the bearing capacity and pile strength design, adopted from the quadrilateral cloth. Choose in embankment design, the article points method to do the embankment stability calculation, at the same time filled with grass of design of the construction and water drainage ditches ready embankment waterproof work, guarantee the excavation slope and embankment slope foot is not affected by water. .Good a graduation design of slope support block plays a crucial role, retaining wall, anti slide pile, sheet pile wall and are of our undergraduates can choose to use the program. This article chooses the gravity retaining wall, by calculating coefficient of active earth pressure, the point of earth pressure is obtained, and the fully the resistive overturning and sliding resistance calculation, make its can well meet the needs of engineering, become a qualifaied design scheme.

Key words:   Foundation treatment; Embankment design; The foundation bearing capacity; Retaining wall
