Abstract

Abstract

The fracture toughness of rock is of great significance in quantitative evaluation of engineering safety and stability. Rocks often destruct with water, so it is worthwhile to do study on the issue as how the rock fracture toughness and associated mechanical parameters change under long-term immersion of reservoir water. In this paper, a long-term immersion test is designed and carried out and a comprehensive analysis is done in aspects such as the fracture toughness, deformation failure characteristics and microstructure change characteristics. The results show that: (1) under the water-rock interaction, the fracture toughness has a significant deterioration trend, and the deterioration rate increased in prophase and lowered in anaphase; and the deterioration rate gradually becomes slow after 5 or 6 months' immersion. (2) The P-CMOD relation curves of the sandstone three-point bending test can be divided into three stages, namely elastic stage, yield stage, and crack development and damage phases; and with the immersion time, the elastic stage gradually becomes shorter, the yield stage gradually becomes longer, and the downward trend of crack development phase gradually becomes slow, meanwhile, the incision opening displacement which is corresponding to cracking peak load gradually increases. The sandstone brittleness gradually weakens, and plasticity gradually enhances. (3) Lubrication, softening and changes of sandstone's inner microscopic structure caused by water-rock interaction, especially the micro-cracks and the development of the cracks are the basic reasons which lead to the deterioration of the sandstone fracture toughness and other mechanical parameters. The research results facilitate the understanding of the degradation law of sandstone fracture toughness under long-term reservoir water immersion.
