Cause Analysis and Treatment Measures for Accidents in the Reinforcement Work of Soft Soil Foundation Embankment
Soft soil foundation is of high natural water content and low shear strength.Embankment on soft soil founda-tion is prone to excessive settlement deformation and cracking.Taking the reinforcement work of the new embankment a-round the Dujiatai flood diversion and storage area as an example,possible causes of cracks in the reinforced embank-ment on soft soil foundation are analyzed.The results show that besides the influence of the soft soil foundation,the fill-ing rate of the embankment construction and the loading on the embankment top are also important reasons for the occur-rence of cracks.With the re-checking and correction of the parameters,a final reinforcement construction scheme is de-termined with the back calculation parameters that the embankment should be reinforced after four years of operation.Practice shows that the embankment has been operating well as for now,indicating the treatment measures to arrange ter-races and strengthen foundation with pond filling are appropriate for new embankment.
