Rock Fracture Spacings, Openings, and Porosities
The amount of grout to inject into a given volume of fractured foundation rock depends on the fracture porosity and on the spacing and sizes of fracture openings. These properties cannot...

Wall Effects in Permeameters
The effect of a permeameter wall on the mean flow velocity measured in a permeameter containing granular material is investigated. The difference between the measured mean flow velocity...

Rock Properties Interpreted from Sonic Velocity Logs
A comparison of sonic velocities obtained by geophysical logging methods with core values of porosity, static Young's modulus, and ultimate strength indicates that relationships...

Engineering Properties of Simulated Lunar Soils
To provide basic engineering data on the behavior of soils under lunar environmental conditions, experiments were performed to determine the properties of soils believed to be representative...

Functional Design of Rapid Sand Filters
Water quality and operating practicability must be the aims in rapid sand filter design. The following design variables are examined to determine how their manipulation by the designer...
