| Abstract: | Based on the phenomenon of the plastic vertical drain brought back from the soft clay ground in surface soft clay, this paper introduces the plastic vertical drain installation technique; Summarizing the advantages and disadvantages of the different technique, and considering the practical situation of engineering, a new method was presented. This method is effective to the surface soft clay improvement, the phenomenon of the plastic vertical drain brought back from the soft clay ground is completely solved with a installation ration of over 80%. It has an advantage of easy operation but low cost, which can be adopted by the similar soft clay improvement engineering. |
