Ratio of Unconfined Compressive Strength of Undisturbed Sample to Remoulded Sample

The ratio of unconfined compressive strength of an undisturbed sample of soil to that of a remoulded sample, at the same water content, is known as sensitivity.

Explanation

The sensitivity of a soil is an important property that helps to determine its behavior under different conditions. It is defined as the ratio of the unconfined compressive strength of an undisturbed sample of soil to that of a remoulded sample, at the same water content. In other words, it is a measure of how much the strength of a soil is affected by disturbance.

Sensitivity is an important parameter for geotechnical engineers because it helps them to predict the behavior of soil under different loading conditions. It is particularly important in areas where the soil is prone to liquefaction, such as earthquake-prone regions.

A high sensitivity value indicates that the soil is easily disturbed and its strength is greatly affected by disturbance. This can lead to instability and failure of structures built on such soil. On the other hand, a low sensitivity value indicates that the soil is more stable and less affected by disturbance.

Conclusion

In conclusion, the ratio of unconfined compressive strength of an undisturbed sample of soil to that of a remoulded sample, at the same water content, is known as sensitivity. It is an important parameter for geotechnical engineers as it helps to predict the behavior of soil under different loading conditions. A high sensitivity value indicates that the soil is easily disturbed and its strength is greatly affected by disturbance, while a low sensitivity value indicates that the soil is more stable and less affected by disturbance.
