改良土静强度试验及结果分析

STATIC STRENGTH TEST ON IMPROVED SOIL AND ITS RESULT ANALYSIS

本文研究了粉粘土及粘土在加入不同配比的石灰、水泥、粉煤灰时的静三轴强度的变化规律 ,通过分析比较 ,得出了不同掺合料的掺合比与强度的关系 ,为设计、施工及养护提供可靠的依据 。

This paper discussed the changes in the static triaxial strength of silty clay and clay mixed with lime, cement and fly-ash at different mixture ratio. The relationship between mixture ratio and strength of different mixtures was obtained through analysis and comparison.Such results could provide a reliable guideline for design, construction and maintenance of the subsoil to assure the requirements be met for the subgrade bed of high speed railway and embankment fillings below the subgrade bed.
