Strength of Soft Clay Reinforced with Square and Triangular Pattern Encapsulated Bottom Ash Columns

Soft clay is known as problematic soil that consists of low shear strength, low permeability and high compressibility where the existing soil on the given site is unable to carry the load of proposed structure by itself, so the use of ground improvement is necessary. The stone columns are increasing...

Civil engineering (General) Soft clay is known as problematic soil that consists of low shear strength, low permeability and high compressibility where the existing soil on the given site is unable to carry the load of proposed structure by itself, so the use of ground improvement is necessary.

It can be concluded that the shear strength parameters were improved based on the different diameter and the height of the column. 2016 Conference or Workshop Item PeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/13124/1/Strength%20of%20Soft%20Clay%20Reinforced%20with%20Square%20and%20Triangular%20Pattern%20Encapsulated%20Bottom%20Ash%20Columns.pdf application/pdf en http://umpir.ump.edu.my/id/eprint/13124/7/fkasa-2016-muzamir-Strength%20of%20Soft%20Clay%20Reinforced%20with%20Square.pdf Muzamir, Hasan and Nurul Aina, Husaini and Norhayani, Pangee @ Mohd Nor (2016) Strength of Soft Clay Reinforced with Square and Triangular Pattern Encapsulated Bottom Ash Columns.
