ASCE 62-16,63-16 AND 64-16 PDF Download

The text you provided describes the standard ASCE/EWRI 65-17, titled "Calculation of the Saturated Hydraulic Conductivity of Fine-Grained Soils." This standard is part of a series that aims to enhance the probabilistic characterization and understanding of saturated hydraulic conductivity. It provides guidelines for calculating the saturated hydraulic conductivity, permeability, and porosity of fine-grained soils.

The calculation method outlined in this standard involves four components: strain-stress data from a step-load test, one-dimensional vertical consolidation theory, the relationship between saturated hydraulic conductivity and the coefficient of consolidation, and the relationship between saturated hydraulic conductivity and permeability, as well as porosity and the void ratio of the soil.

The methodology presented in this standard can be applied to improve various calculations related to land subsidence, groundwater flow prediction, and the transport of dissolved solutes in groundwater. However, it is important to note that this standard's methodology is specifically intended for use with fine-grained, compressible, inorganic soils. Highly organic soils, such as peat, exhibit anomalous consolidation behavior and are not covered by this standard.
