With the rapid development of Chinese economy, the new technology has been a large passenger special line. Especially the economy developed coastal areas, but these areas have soft soil, passenger transport through the inevitable for soft soil area, so the design of embankment PDL, has the vital significance.
Soft soil area, the strength of PDL embankment design is no longer control factors, the key is to control post-construction settlement. In this paper the beijing-shanghai railway a soft soil foundation reinforcement design for settlement of foundation treatment, after the stability, remote-control device after screening, embankment construction and the design of deformation monitoring. Settlement calculation by delamination summation-method and slope stability calculation method is used, through the calculation of points, unprocessed foundation stability is not meet requirements, Using CFG pile composite foundation, stability and settlement after can meet the requirements. Through calculation, is very suitable for CFG pile of soft soil foundation treatment plan, And put forward the settlement after construction measures. Embankment deformation monitoring including monitoring purposes, requirements and contents. After inspection, the design is the basic requirements of the design, can be used as a kind of simple construction or references.
