Experimental Study on Controlled Modulus Column Methods

When embankments are constructed on soft ground, they may encounter settlement and/or stability problems due to low strength and high compressibility of the soft ground. To overcome these difficulties, a controlled modulus column method can be used for the construction of embankments on soft soils. This technology takes advantages of various ground improvement concepts, such as densification, reinforcement, solidification, etc. An experimental study was conducted in the laboratory to investigate the behavior of the controlled modulus columns.
