摘要： CFG桩复合地基已经在地基处理中得到了极其广泛的应用。针对某工程事故，着重从工程地质、水文地质、施工方面以及破坏准则-格里菲斯理论等方面进行事故原因分析，为今后CFG桩复合地基的安全应用提供参考和借鉴。

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
