Accurate and fast numerical modelling of the borehole heat exchanger (BHE) is required for simulation of long-term thermal energy storage in rocks using boreholes. The goal of this study was to conduct an in situ experiment to validate the proposed n

With increasing pressure to reduce the fraction of energy coming from fossil fuels, there is an increased need for research into feasible and sustainable energy sources, such as solar energy. The problem with solar energy is the mismatch between supp

This paper presents the fundamental solution for a two-dimensional displacement discontinuity method (DDM) for transversely isotropic elastic materials. We follow the procedures shown in the literature, in which there are some typographic errors and

The primary goals of the experimental work described in this paper were to establish the in situ spalling/damage strength of the intact rock, to establish the state of the in situ stress, and for the work to act as a Prediction–Outcome exercise wit

Bsed on the recent observations from two underground laboratories, the construction-induced excavation damage zone (EDZ CI ) caused by explosion or by mechanical excavation and stress-induced excavation damage zone (EDZ SI ) are distinguished. The ke

Seasonal storage of solar thermal energy is an attractive way to utilise the underground space to increase the share of renewables and tackle the global challenge of climate change. One of the methods to store the solar energy is the borehole thermal

An in situ concrete spalling experiment will be carried out in the ONKALO rock characterization facility. The purpose is to establish the failure strength of a thin concrete liner on prestressed rock surface, when the stress states in both rock and c
