Abstract

Abstract: The cement, fly ash and gravel (CFG) columns are widely used as composite ground for the multistory buildings, highrise buildings, and industrial facilities due to their cost effective and easy installation advantages. This paper presents the factors that causing the defected CFG columns from the site geotechnical and hydrological conditions as well as the construction procedures. The Griffith Failure Criteria are used in the analysis.

Key words: engineering geology, hydrological geology, griffith failure criteria
