An Experimental Study on Settlement due to the Mutual Embedding of Miscellaneous Fill and Soft Soil
Settlement deformation in the foundation with miscellaneous fill and soft soil was typically calculated by summing up the settlement in each individual layer. However, this calculation method did not involve settlement deformation by embedding miscellaneous fill particles into soft soils under exter...
