Loading Rate Dependency of Uniaxial Compressive Strength of Rock Under Water-Saturated Condition.

Abstract

Moisture has various effects on the behaviour of rocks. It is well known that the compressive strength decreases significantly with an increase of moisture content. Though many studies have been carried out concerning the effect of moisture, the influence on the time dependent behaviour is still open to discussion. It is very important to clarify its time dependence for analysing the long-term stability or durability of underground structures.
