Analysis of Soil-squeezing Effects in Mixing Pile Construction

The deep mixing pile, which is a new groundwork construction method, generally used in soft soil, is being widely popularized in foundation construction fields. It has been proved that mixing pile construction would also cause soil-squeezing effects.On the basis of research and analysis by former scholars, the monitor data of wall lateral displacement and pipe sedimentation related to an engineering project are analyzed and the characteristics of the soil-squeezing effects as well as the rules of it are summarized under different construction crafts. Finally, these rules are researched by the formulas of displacement based on Sagaseta's source-sink image technique.
