“…The sensitivity of BEC to stress in crystalline rock is well documented at the laboratory scale beginning with seminal studies in the 1960’s (Brace, 1975; Brace & Orange, 1966; Brace et al., 1965; Kaselow & Shapiro, 2004). Laboratory scale induced polarization studies have since revealed the sensitivity of frequency dependent complex conductivity to stress perturbations in crystalline and non‐crystalline rocks, and in unconsolidated sediments (Glover et al., 2000; Lockner & Byerlee, 1985; Niu et al., 2017; Saneiyan & Slater, 2021). However, the demonstrated potential of induced polarization monitoring under transient stress conditions has not been fully realized due in large part to challenges associated with collecting high fidelity field‐scale data, especially in cross‐hole imaging configurations.…”

Fluid flow through fractured media is typically governed by the distribution of fracture apertures, which are in turn governed by stress. Consequently, understanding subsurface stress is critical for understanding and predicting subsurface fluid flow. Although laboratory‐scale studies have established a sensitive relationship between effective stress and bulk electrical conductivity in crystalline rock, that relationship has not been extensively leveraged to monitor stress evolution at the field scale using electrical or electromagnetic geophysical monitoring approaches. In this paper we demonstrate the use time‐lapse 3‐dimensional (4D) electrical resistivity tomography to image perturbations in the stress field generated by pressurized borehole packers deployed during shear‐stimulation attempts in a 1.25 km deep metamorphic crystalline rock formation.

“…Jiang et al [17] observed variable relative humidity inside the URE wall due to the different humidity on both sides of the wall. Saneiyan and Slater [26] found that water increases the electrical conductivity of soil, and Abdulsamad et al [27] provided a method using electrical conductivity to image the change in water content of URE walls. Dong et al [25] observed that the thermal performance of rammed earth structures varies with ambient air conditions.…”

Waterproof capacity, thermal isolation, and pushover strength are the main characteristics when an unstabilized rammed earth (URE) wall is constructed. In this paper, a comprehensive numerical simulation model is built to evaluate the effect of 15 different factors on those three aforementioned properties of URE walls. The simulation results show that the hydraulic, thermal, and mechanical properties of the wall are interconnected. It is found that the waterproof capacity of the wall can be mainly improved by increasing the dry density, decreasing the rising damp effect, and reducing the fine content value of the wall. The thermal insulation characteristic of the wall can be ameliorated by increasing the wall thickness and reducing the rising damp effect, fine content, and dry density. In addition, the pushover capacity of the wall can be strengthened by increasing the wall width, fine content, wall thickness, and vertical load and decreasing the rising dampness and wall height. In addition, time has a positive effect on the waterproof capacity, thermal insulation, and mechanical strength of URE walls. These properties change significantly in the first 100 days and then stabilize after 180 days for a typical URE wall. Eventually, a new theoretical approach is proposed to predict the long-term THM behavior of URE walls by considering the 15 factors in its framework.
