According to the soft base embankment engineering, the dynamic drainage consolidation method combined with the strong tamping and heaped pre loading are presented, and construction method, construction technology,side control measure and questions noted in the design and construction are discussed.

The stability of urban deep-thick soft soil embankment subgrade is worse and its set- tlement is larger.

The consolidation of soft soil embankments is an actual problem often encountered in railway design and construction.

Through comparing the unreinforced embankment with the reinforced one,and analyzing the change of the elastic modulus and single geotextile position,and the optimal geotextile position and geotextile layers,the displacement effect of the soft soil embankment reinforced with geotextiles is studied.

During the construction of embankment on soft soil ground, people are accustomed to small deformation hypothesis, namely the hypothesis soil body subsidence deformation enough slightly, such hypothesis may simplify the question very good and has the good serviceability in practical.
