摘　　要：有机质含量,是影响地基土物理力学性质的重要因素之一,对评价地基土的岩土工程性质具有重要的意义。本文通过对印度尼西亚某地同一试样不同温度下(105℃和68℃)天然含水率的差值、试样在105℃烘干后液限与天然土液限差值及重铬酸钾容量法测定试样的有机质含量值进行相关性研究,为该地区地基土中有机质含量的估算提供借鉴,期望能为当地以后的工程建议提供参考。The content of organic matter is one of the important factors affecting the physical and mechanical properties of cohesive soils, and is very important for evaluation of the geotechnical properties of base soil. This paper presents a study on a sample obtained from a port side in Indonesia, based on the analysis of the difference in water content in the same sample at different temperatures（105 ℃and 68 ℃）, and the difference in liquid limits between the natural soil and the soil sample dried at 105 ℃, and the organic matter content determined by potassium dichromate method and study on their correlations. The study can provide reference for the estimation of organic matter content of cohesive soil in this area, in the hope that the reference may be helpful for future construction works in the area.
