Effects of hydrothermal treatment on dynamic properties of granite containing single fissure subject to impact loading

The largest potential of geothermal energy lies in the hot granitic basement rocks with low permeability deep in the earth. Deep granitic rocks are usually exposed to the coupled water and thermal environment over a long period of time, as well as dynamic disturbance caused by drilling and excavation. Understanding the influence of low temperature water on rock is of great significance for effectively developing complex fracture network and...
