Test Method Title
Triaxial Compressive Strength of Undrained Rock Core Specimens Without Pore Pressure Measurements
Reference Number
AASHTO T 226
Material
Rock
Test Property
Shear Strength, Young's Modulus, Angle of Internal Friction
Description of Test
This test method covers the determination of the strength of cylindrical rock specimens in an undrained state under triaxial compression loading. The test provides data useful in determining the strength and elastic properties of rock. Rock is known to behave as a function of the confining pressure. The triaxial compression test is commonly used to simulate the stress conditions under which most underground rock masses exist.
Number of Test Specimens
1 or more
Test Specimen Size
Right circular cylinder, with diameter of at least 1 7/8 in and a length to diameter ratio of 2 to 2.5:1
