ROCK MECHANICS

Rock Mechanics Laboratory is equipped for evaluating following properties of rock samples.

 Physical Properties

• Water Absorption

• Density & Porosity

• True Specific Gravity

• Slake Durability Index Test

Engineering Properties

• Point load strength index

•  Brazilian tensile strength

• Unconfined compressive strength

• Triaxial shear strength

In addition to laboratory testing in-situ tests for evaluating following rock mass properties are conducted.

• Deformability

• Joint shear strength

• Passive resistance

• State of stress

• Pull-out resistance of anchors

• Foundation Pull-out Tests

• Rock mass classification

 Important Investigation Undertaken 

• Foundation Pull-out test at 400 kVTransmition Line Towers Solapur - Sangli (Maharashtra).

• Plate load test at Panchana Irrigation Scheme, Karauli (Rajasthan)

• Bearing capacity test at Ranganadi Hydro-electric Project, Yazadi, (Arunachal Pradesh)

• Anchor pull out test at Indira Sagar Project, (Madhya Pradesh)

Important Research Studies Undertaken 

• Effect of asperity on shear strength of jointed rock

• Evaluation of static and dynamic elastic properties of rocks met with in Gujarat.

• Geo- mechanical  model studies to understand behaviour of jointed rocks.

• Evaluating pullout capacities of the anchors installed in the stilling basin bay - 3 of SSP Gujarat.

• Effect of water on unconfined compressive strength of limestone.
