含水量对非饱和土强度的影响规律与机理探析

Influence of Water Content on the Strength of Unsaturated Soil and Its Mechanism

工程中含水量的变化对非饱和土的多项性质作用明显,文章在总结前人对非饱和土强度预测的理论和公式、利用三轴仪进行非饱和土强度试验的基础上,得到了广义强度指标与含水量之间的关系,拟合出合理的应用于非饱和土强度计算的公式,可使非饱和土的工程实际问题更加简单易行。

The change of water content has great influence on unsaturated soil strength,and then can affect its engineering properties.By summarizing previous theories and formulas for predicting the strength of unsaturated soil,using three axis instrument based on unsaturated soil strength tests,the paper finds out the relationship between generalized strength index and water content,and fits out the reasonable application of calculation on the strength of unsaturated soil formula,which makes the actual problem of unsaturated soil engineering more simple.
