摘要:本次设计的题目是郑西高铁地基处理与路堤设计。在地基处理中,主要选用的是CFG桩复合地基承载力验算,选用的是400mm桩径,确定了承载力和桩体强度设计,采用了四边形布距。在路堤设计中,选用了条分法做了路堤稳定性的验算,同时用草灌喷播施工以及截水沟的设计做好了路堤的防水工作,保证挖方边坡和填方坡脚不受流水冲刷。好的一份毕业设计边坡支挡起着至关重要的作用,挡土墙、抗滑桩、预应力锚索、桩板墙等都是我们本科生可以选用的方案。本文选用的重力式挡土墙中,通过计算主动土压力系数,从而得到土压力的作用点,以及对其抗倾覆和抗滑移性做了充分的验算,使其能很好的适应工程需要,成为一份合格的设计方案。33086

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
