Abstract Abstract：Research purposes：It is a problem to choose economic and reasonable method of soft soil ground treatment to meet the strict standard of differential settlement of high-speed railway engineering. The differential settlement of soft soil ground treated with dry jet mixing pile, deep cement mixing pile, vacuum preloading combined with heaped preloading, plastic drain belt combined with surcharge preloading, sand pile combined with surcharge preloading, among soft soil ground, bridges, and culverts, were studied through the field test in high-speed railway.
Research conclusions：(1)The methods of soft soil ground treatment and type of structures have great influence on residual longitudinal differential settlement. (2)The transverse differential settlement changes greatly during 3 months after embankment being filled. The transverse differential settlement will not do harm to train with a longer period of preloading. The load is not a main factor to residual longitudinal differential settlement.
(3)It should be avoided to changing method of soft soil ground treatment in same site. The transition area should be adopted among embankment, bridges, culverts, and soft soil ground treated with different methods.
(4)The research results can be used in the design and the construction of high-speed railway.
