The overconsolidation ratio (OCR) is a qualitative indicator of this densification or stiffening of the soil, and it is defined as the ratio of the maximum overburden stress ever experienced by the soil (i.e., with the ice sheet on top) to the present overburden stress (i.e., without the ice sheet).

2024年7月21日 · The Overconsolidation ratio, also called OCR, is defined as the ratio of the preconsolidation stress, that is the maximum value of effective stress the soil has ever experienced, to the present effective stress.

medium overconsolidation ratio offshore inorganic clays derived from a high quality database. These properties, such as preconsolidation stress and undrained shear strength, are required for design of most offshore infrastructure and for assessment of …

Overconsolidation ratio (OCR) is often defined as the ratio of the maximum past effective consolidation stress and the present effective overburden stress: For mechanically overconsolidated soils where the only change has been the removal of overburden stress, this definition is appropriate.

2023年7月14日 · One of the critical parameters that play a crucial role in geotechnical design is the Over Consolidation Ratio (OCR). It is the ratio of the maximum effective vertical stress that a soil has experienced in the past to its current effective vertical stress.

2024年10月28日 · Calculation Example: The Overconsolidation Ratio (OCR) is a key concept in soil mechanics that quantifies the degree to which a soil has been overconsolidated. It is defined as the ratio of the pre-consolidation pressure (σ’c) to …

2024年2月14日 · Calculation Example: The overconsolidation ratio (OCR) is a measure of the degree to which a soil has been overconsolidated, or compressed, under a load. It is defined as the ratio of the preconsolidation pressure (P_c) to the effective overburden pressure (P_0).

1997年1月31日 · ABSTRACT: The overconsolidation ratio (OCR) of a soil is important in that the ratio affects the initial stress state and the compression and shear behaviour of the soil. The assessment of the OCR traditionally by means of oedometer tests on "undisturbed" samples has not always been successful due to inevitable sample disturbance.

2024年9月26日 · This calculator provides the calculation of overconsolidation ratio (OCR) for geotechnical engineering applications. Explanation Calculation Example: The overconsolidation ratio (OCR) is a measure of the degree to which a soil has been preloaded or overconsolidated.

2018年6月1日 · Overconsolidation ratio (OCR) is commonly used in different geology disciplines. It is considered crucial for proper evaluation of engineering-geological properties of soil.
