Title:
COMPRESSIVE AND TENSILE TESTING AT ORIGINAL POSITION OF ROCKBED
Document Type and Number:
Japanese Patent JPS62148712
Kind Code:
A
Abstract:
PURPOSE: To eliminate the needs to deliver rock specimens of overmuch weight to a laboratory by testing the rockbed at the original position.
CONSTITUTION: The surface of rocked in a place to be tested is finished to flat surface, and an inner groove 3 and an outer groove 5 are excavated in the rockbed in such a way as to surround the rockbed concentrically. The rock between the inner and outer grooves 3 and 5 is crushed and removed to form a columnar specimen 6 and a round groove 7 in the rockbed. A loading frame 8 on which a loader 9 for the specimen 6 is put is set in the groove 7. A compressive and tensile testing can thus be made without the needs to deliver rock specimens 6 to a laboratory.
